Why is a small hole gauge sometimes referred to as a transfer gauge?

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.

The sum of the normal stresses does not change as the stress state rotates through an angle. a)-trune b)- false

Apressure vessel with an r/t 20 cannot be treated as thin walled vessel. a)-trune b)- false
