Very good explained. God blessed you .

[@VehiclesBro]

We are waiting for more videos like this. Your knowledge is too good & you are doing great job by distributing your knowledge. Plz keep continue it💐💐

[@SandeepAcademy9]

Planning to upload at least one video each week. Lets us see how much I can deliver !

[@adityashekhar1090]

Exceptional. I'm a pilot and compressor surge wasn't explained this nicely in Oxford or cohen rogers

[@bipintandel8358]

Excellent sir ji. 🙏🙏🙏🙏🙏

[@uks1989]

Anti Surge valve (Discharge to Suction) is provided to mitigate Surging of Centrifugal Compressor.

[@AdityaGoel-cp5no]

Hi Sandeep. Very nice explanation. Please also mention the literature/ reference material that you referred to prepare this video. Thanks for all the effort Sandeep!!!!

[@rishuraj8824]

Doing great job. Kindly make video on practical compression surge mitigation

[@srivathsa1848]

If you listen to him, I can guarantee you can excel in any interviews. No Master courses or Mtech will teach with this clarity

[@sonam4157]

Excellent

[@ikbalgazi9163]

Wonderful explanation

[@warishmotiwala344]

Amazing and excellent information.

[@y.s8916]

Excellent sir...Sir I'm working in Ammonia plant which has turbine driven air , ammonia refrigeration and syn gas compressors. Can you suggest sir from where I should study about compressors and turbines??

[@DanishAli-wx9dh]

Hello Bro.... I'm also working at ammonia plant, can we discuss about our working on same domain! I have some questions about compressors , would you help me to sort out.

[@yogeshpatel246]

Sir, please upload video in details for settle out pressure of comp.

[@nisargrathod2811]

I can't understand what is delta P which point's diffrence

Sir fluid machineries jese ki pumps and compressor ke liye kuch acche se books recommend kr dijiye please...

[@silentmanqateri]

More about surging

[@Saivisak]

Hi Sandeep please post this video with english subtitles

[@thomasmathew4469]

I have a doubt if the compressor operating point would shift to E in case of surge. Because if it can automatically reach the -ve slope it reaches the stable area and the operation would continue based on system resistance . I feel the cycle of surge would be ABCD-DCBA, not to E

[@saikiran-zq7bs]

Please mention reference books in the description.

[@riteshkadam5258]

U r genius

[@user-sherf]

Hi friend do you have any PLC logic for surge protection to share??? Using Differential pressure

[@ravindrashukla8933]

Excellent sir 👍

[@jaydeepsinhmahida494]

Sir please make video related to gate... Or related to Ipc... Thank you!!

[@SandeepAcademy9]

Characteristic curve and performance curve is important for GATE also. Surging may not be important. But part 1 was important and next 2 videos which will be uploaded are important.

[@faisaljummal8101]

Very excellent

[@thomasmathew4469]

what is the effect of MW on discharge temp ?

[@akshpatel2868]

Sir me Compressor and Blower ke bich ka difference ap ke pas se sun na chahunga. please sir

Sir please make a vedio on job profile of junior engineer assistant IV (production) in petrochemical industry and refineries

[@harshilzinta]

Sir ekk doubt tha Jab unstable condition me flow suddenly increases mass flow rate from B to E, then the pressure of reservoir now increases and (delta p) required now again increases. So the mass flow rate will have to decrease in order to reach an increased pressure at reservoir. But now as the mass flow rate is decreased, now the flow the pressure of reservoir will decrease and pressure required decrease of compressor so the mass flow rate now increases and keep the system in stable condition . So sir even after we started with an unstable condition we further reached a stable condition. So sir am I wrong? And if I am wrong please correct me

[@akhlaqueahmad9961]

Good sir

[@nisargrathod2811]

What is Delta P i have doubt in this

[@kalyanroy7653]

SIR AGAR RESERVOIR ME MASS ACCUMULATE HOTE REHEGA WAISE PRESSURE REQUIREMENT V BADEGA. SO AGAR STABLE REGION ME V HO, COMPRESSOR MASS FLOW RATE LOW KARKE HIGH PR RATIO ACHIEVE TO KAR LEGA BUT WO EK MAX POINT TAK HE KAR PAEGA TO, USKE BAAD TO FIR V RESERVOIR KA PRESSURE BADEGA TO TO STABLE REGION ME V BACKFLOW HO SAKTA.

[@arghyadhar662]

hi Sandeep, if the compressor has stable operation although it shifts to point 2 or 3 from 1, why will it not have a stable operation once it reaches point E? What is the criteria for a point to be like point E on characteristic curve so that although it is in stable operation zone but it does not behave like point 1?

[@parthparmar6687]

@arghyadhar662 Sir i think previous case it was kind of step chnage while for state E was reached instantaneously like and the flow is so high enough that the pressure requirement for compressor is again achieved to point A and still is not enough so backflow occurs from downstream to compressor and again reaches to unstable operation

Brother what is net inhand salary in Hpl। I also got selected this year । They have written around 5 lakh during trainning period।how much i can expect monthly

[@akhlaqueahmad9961]

Sir PSV,TSV&PRV me Kya difference h

[@rajkamal.achanta]

As far as i know.. PSV is pressure safety valve . it suddenly opens after reaching a certain pressure setpoint. TSV is temperature safety valve . it opens suddenly after reaching a certain temperature. ( both psv and tsv open due to pressure build up but psv is rated for certain pressure .. And tsv is rated such that the valve opens if system reaches pressure corresponding to setpoint temperature) PRV is pressure relief valve.. It gradually opens with increase in pressure and closes gradually with decrease in pressure..

[@dhruvpatel9012]

Sir, kya positive displacement type compress me surging problem ho Sakta he ? And in centrifugal compressor surging ho rahaho to use in process kese roke ? Can NRV helps in avoiding surging ?

[@mhttwr]

Surge is happening due to centrifugal action only so PD compressor will not face surge. NRV may protect back flow but what about piping between NRV and Compressor discharge (cooler in between), hence anti surge valve is provided between compressor cooler and NRV to transfer backflow towards suction drum of compressor.

[@PragatiTripathi-ul3mq]

Sir chemical engineering me coding sikhna required hota h kya ?

[@souravmondal6686]

No

[@onkarreddy3789]

Kya padaya sir aapne...aise surging ke upar ek bhi video nahi KZbin pe

[@007ashumishra]

Hi Sandeep, you tried hard to explain, well effort. I found, you made it complicated probably because of pressure to yourself prove best than other youtube videos, and a professor from IIT (mentioning his name was unethical, and non-professional). It could be more easy which can leave the impression in mind instead of getting confuse because of mentioning N number of times pressure low, pressure high. You should have the function of valves at discharge while explaining the terms. See this video, a simple way to get know the function kzbin.info/www/bejne/r3rPoah6mtZ0mMU

[@SandeepAcademy9]

First of all, Let me clear you that I have great respect for Prof. S.K.Som for his knowledge and way of teaching. You might be very new on this channel that’s why you don’t know this. I have mentioned and recommended in many videos about Prof. S.K.Som lecture. I myself have learned Thermodynamics from his lecture only. My subscribers know these fact. In this video also I have said He is very learned professor. Only thing is that I liked the explanation of surging in the book of Centrifugal compressor more than any other source. So I explained in that way only. If you find other explanation are easy. Then it is perfectly OK. After all concept should be clarified. Source does not matter. There is no pressure to prove best. I am in learning phase, I can’t be best. And at least no comparison from Prof. s.k.som. He is like Guru. Sorry for your miscommunication and wrong interpretation.

[@ParkJimin-rg3zy]

​@@SandeepAcademy9sir dont listen to this.people you are best and just no one explains as simply you do even not iit professors so for me you are more precious then any iit professor ❤

[@SandeepAcademy9]

@@ParkJimin-rg3zy Thanks for your kind words. But Prof. S.K.Som was really great.

[@LaluYadav-cv1vt]

Why run centrifugal compressor on polytropic process or can run on another process?

[@SandeepAcademy9]

Isothermal process is very difficult to achieve. Adiabatic process are less efficient. More work required for same compression. In reality compression happened in between these two extreme, called polytropic process.

[@LaluYadav-cv1vt]

Thanks 🙏🙏🙏 guru ji
