A circuit contains four 100 ohm resistors connected in series. If you test the circuit with a dmm you should read a total resistance value of A. 250 ohms.
B. 1000 ohms.
C. 400 ohms.
D. 100 ohms

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.
