Sir.... Ur amezing. I like ur the way of teaching and communication skills

[@raheelmalook5884]

Sir if we get negative value of Vw2, should it be taken negative in formula or should the negative value be discarded?

[@Abu-cs7ny]

It's ok further that value will become in positive

Q The following data related to propose a hydroelectric system such as Head is equal 30m ,catchment area 500 km^2 , rainfall 140 cm per year, percentage of total rainfall utilise 68% and penstro efficiency 95% ,turbine efficiency 85% ,generator efficiency 86% and load factor 44% calculate power developed and suggest suitable machine and specify the same

[@ashutoshkumarsharma9932]

sir i think beta will be 180-160 instead of fi as the angle of deflection is measured between V2 and the tangential velocity of vanes (u) , please clarify

[@gmeena1]

I think you are right,

[@ashyunthapamagar6951]

Make clear on that calculation for Vw2

in actual condition ,how we can get the value of mean bucket speed ? thank you

[@aamirhussain7134]

Why is angle beta taken to be acute..?

Sir please solve this question how it solve in a stage of impulse reaction turbine, steam enters with a speed 245 m/s, at an angle of 30 in the direction of blade motion. the mean speed of blade is 145 m/s, when the rotor is running at 300 r.p.m. the blade height is 10c.m. the specific volume of steam at nozzle outlet and blade outlet are 3.45 m3/kg and 3.95 respectively. the turbine develops 287 kW of power. assuming the efficiency of nozzle and blades combined considered is 90% and coefficient of discharge 0.8. find (1) the enthalpy discharge in each stage. (2) degree of reaction. (3) stage efficiency.

very nice

[@sravanisravya4832]

Sir please give me total hydraulics subject notes sir like theory and problematics sir

[@surendrachoudhary8274]

Sir iss m angle 160 to cos20 kyu le rhe h

[@adnankhan-sp7uu]

Sir make the video in urdu plz I don't understand. Thank you sir

[@thodahasbhiliyakaroyaro9525]

Nice

[@ankuryadav1615]

is in above question vr1=vr2 ? then how ?

[@akash1000]

Then it's not Pelton wheel

[@thodahasbhiliyakaroyaro9525]

Ese based conventional question

[@sharifaakter1122]

thx sir!!! its realy hepful

[@bangarichatan8969]

Nice
