Ahydraulic turbine has 50m of head available at a flow rate of 1.30 m^3/s, and its overall turbine. generator efficiency is 78 percent. determine the electric power output of this turbine. given that ρ=1000 kg/m^3

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false

Ariver flows from north to south at 8 km/h. a boat is to cross this river from west to east at a speed of 20 km/h (speed of the boat with respect to the earth/ground). at what angle (in degrees) must the boat be pointed upstream such that it will proceed directly across the river (hint: find the speed of the boat with respect to water/river)? a 288 b. 21.8 c. 326 d. 30.2

Determine whether or not it is possible to compress air adiabatically from k to 140 kpa and 400 k. what is the entropy change during this process?
