That's a smart description, Thanks a lot!

Nice video. What is sensible and latent heat in the Earths atmosphere?

👍

Hi, thanks for the video. Can I ask how you model vertical fins that are not perpendicular to the wall. For instance vertical fins that project off the wall at 45°. I cannot find any facility to model this. Any help appreciated.

Great video hats thanks ❤

Please Indians stop making engineering videos everything u teach is wrong

Who is this guy ? Bro go home 😂

Irrelevant Questions. Nothing to do with ASHRAE CHD Exam.

Thank you for simplifying this video. Kudos!

19:34

Thank you very much for the explanation and efforts.

I think also in the case of a pump below the suction point at the base of a reservoir tank, the fluid head in the tank should be considered as well

Thank you for such a clear and easy to follow presentation

What if the suction source is above the pump?

Very very clear video. Thank you. After your video, I could better understand the emagramme .

At 21:14 on Your presentation "NPSHr > NPSHa " . it is not correct for the NPSHr (Net Positive Suction Head required) to be greater than the NPSHa (Net Positive Suction Head available). In fact, for a pump to operate properly and avoid cavitation, the NPSHa must be greater than or at least equal to the NPSHr. This can be expressed as: NPSHa≥NPSHr If the NPSHa is less than the NPSHr, the pump will likely experience cavitation. Cavitation occurs when the pressure in the pump falls below the vapor pressure of the liquid, causing the liquid to vaporize and form bubbles. These bubbles can collapse violently when they move into higher pressure areas within the pump, potentially causing damage to the pump impeller and other components, reducing efficiency, and causing noise and vibration. To ensure safe and efficient pump operation: NPSHa: The actual pressure head available at the pump suction, considering atmospheric pressure, static head, velocity head, and subtracting vapor pressure and friction losses. NPSHr: The minimum pressure head required by the pump to avoid cavitation, specified by the pump manufacturer. Always make sure that: NPSHa≥NPSHr Anyway your presentation is excellent .... Thank you so much.

அருமை, நன்றி.

Great effort for animated presentation. For correction, rotation arrow is supposed to be counter flow or backward-inclined flow. As per Bernouli's principle when the velocity increases the pressure should decrease to balance the flow. And to avoid cavitation pump NPSH-R should be less than to what is available (NPSH-A)..Ergo NPSH-A > NPSH-R..Nicely presented just need some corrections.

Thanks for your remarkable efforts brother 💯

many thanks for This video and all information but i have a notice NPSHA always bigger than NPSHR

ஆன்சர் 😊

Simplified presentation

Well presented

Useful presentation

Best video I have watched on refrigeration cycle. Thank you

❤❤

Very good!

Great video 👍

Please upload more videos about mechanical seal, and glass lined reactor

Appreciation for this nice explanation

Beautifully explained. Anyone can understand each basic concepts.

How come velocity and pressure can be increased at the same time 🤔

Shouldnt be killing humans though

Please tell me what is valve

Very clear, thankyou ❤

Suction pressure is P2 and not th total pressure ...the dynamic pressure V²/2g should be not added but subtract from Pa🙏

At time 21.14 : please read NPSHa>NPSHr: we will make a detail video on relationships

In last, You said the NPSHR must greater than NPSHA. If available is less than required, how it works?

Ur explanation is also sup

Good information ji sir tq so much for giving this information

Great effort .. hanks for the information .. one point to be corrected if possible: NPSHa > NPSHr

Is it possible to obtain saturated air from unsaturated air without adding any moisture?

Great video and information man. Really helps.

Wow keep it up

I don’t find any use of background music..it’s annoying…edit that

At last you told unsaturted air contain more water vapoure that may be wrong , unsaturted air contain less water vapoure

How many meters can absorb the water in down in pipe

Nice Explanation, Thank you
