Q2. The circuit shown in Figure 1 has seven resistors. The resistors are connected in series as well as in parallel and they are supplied with 32V. Calculate the: Total resistance b. Total current drawn from the supply [3] Potential difference across the R3 and the R7 resistors [4] [10] a. C. R3 = 90 R4 = 80 R1 = 30 Rs = 8a Rs = 40 R2 = 60 R = 32 32V

A2-m rigid tank initially contains saturated water vapor at 100 kpa. the tank is connected to a supply line through a valve. steam is flowing in the supply line at 600 kpa and 300 c. the valve is opened, and steam is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. a thermometer placed in the tank indicates that the temperature at the final state is 200°c. determine (a) the mass of steam that has entered the tank (b) the amount of heat transfer.
