When diagnosing engine noise, Technician A says a mechanical stethoscope may not be appropriate in pinpointing a squeaking drive belt. Technician B says a whirring noise is likely to be from external accessories such as alternators, water pumps and belt tensioners. Who is correct

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.
