A set is set in front of a stream, a 12 m head is obtained and asmall turbine is operated, and it can be directly from the turbineshaft.
By means of a pump that is driven, further cultivation areaslocated 15 m above elevation
irrigation is planned. The flow of water in the turbine line is 0.2m3
/ sec, occurring in the piping system
total irreversible head loss is 3.5 m and the efficiency of theturbine is 70%. The efficiency of the pump used is 80%, itprovides
flow 0.03 m3
/ sec, if the diameter of the pipe is 10 cm and the kinetic energycorrection factor is 1.1, from the pump to the planting areas
Find the total irreversible head loss and lost mechanical energypower in the outgoing pipes.

NOTE: Density of water is 1000 kg / m3 and gravityacceleration.
9,81 m / sn2
take it. Kinetic energy correction factor anywhere
You can get 1.1

I am sending the question to the 2nd question solution is moredetailed and you do not fully understand it, please carefullysolve

又 12 ni T 15ml
