Water flows from a storage tank on a hill to a house 60 feet below. The city code requires a minimum pressure of 20 psi at the tap. Determine the a) velocity of the water at the tap (house) when pressure requirements are met and b) flow rate in the pipe. Neglect losses due to friction, entrance and exit, etc.

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.
