Density of gauge fluid used in well manometer is rho =13600 ±13.6 kg/m3. the maximum height of gauge fluid in the reading scale is h=0.4 m., and uncertainty in reading scale is ± 0.1 mm. compute the absolute uncertainty and accuracy of this well manometer? use g = 10 m/s2, and one digit after decimal point for results only!

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.
