Water with a specific volume of 0.001 m3/kg flows through a pipe at 5 kg/sec entering the pipe with an initial velocity of 100 m/sec and exiting at 50 m/sec. The exit of the pipe is 100 m above the inlet. The pipe is well insulated and the power required is 100 W.The gravitational constant is 9.8 m/s2.

a) Sketch a schematic of the process, make sure to include the boundary and indicate values crossing the boundary.

(b) State the model assumptions.

(d) Find the change in enthalpy of the water in kJ/kg.

(e) Calculate the area of the pipe inlet in m2.
