A15 kw pump receives water from a 5 cm diameter pipe and sends it with a velocity of 3 m / s into a 10 cm pipe. what is the pressure rise of the water?

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.

For a gate width of 2 m into the paper, determine the force required to hold the gate abc at its location.
