The pressure difference between two points along a horizontal pipe, through which water is flowing, is 1.4cm of mercury. If due to non-uniform cross-section, the speed of flow
of water at the point of greater cross-section is 60cm/sec .Calculate the speed at the other
part.

An open feedwater heater operates at steady state with liquid entering at inlet 1 with t? = 40°c and pl = 1 .2 mpa. water vapor att2-200°c and p2 = 1.2 mpa enters at inlet 2. saturated liquid water exits with a pressure of pa 1.2 mpa. neglect heat transfer with the surroundings and all kinetic and potential energy effects, determine the mass flow rate of steam at inlet 2 if the mass flow rate of liquid water at inlet 1 is given as 2 kg/s.
