1 What happens to the current in a circuit if a 20 resistor is removed and replaced by a 0.50
resistor?

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

For a gate width of 2 m into the paper, determine the force required to hold the gate abc at its location.

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.
