Liquid water enters the reboiler at 20C and 5 MPa of absolute pressure. It exists as a superheated vapour at 300C, through a pipe of 40 mm diameter. The pressure drop in the reboiler can be neglected. If the mass flow rate of water is 1000kg/hour and the flow is a steady flow, calculate:

(a) Volume flow rates of water at the inlet and outlet of the reboiler.

(b) Velocity of water vapour at the inlet of the pipe
