A U-tube manometer in Figure 1 is used to measure the gauge pressure of a fluid P of density 850 kg/m^3. If the specific gravity of liquid Q is 13.6, what will be the gauge pressure at A if h1 = 0.6 m and h2 = 0.55 m above BC. Take into consideration Patm = 101.3 kN/m^2.

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.
