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.
(c) c
(d) Find the change in enthalpy of the water in kJ/kg.
(e) Calculate the area of the pipe inlet in m2.
