A boiler receives a flow of 5000 kg/hr liquid water at 5 MPa, 200C and it adds energy to the flow to exit state of 4500C, 4.5 MPa. Determine the necessary minimum pipe flow area for inlet and outlet pipes. The velocity of water is maintained under 20 m/s. If this boiler is to operate on Moon, discuss two major design changes in this type of boiler.
Given properties of water :
Vinlet = 0.001 m3 / kg
Vexit = 0.0716 m3/kg
