As an electrician on the job, you encounter an installation that is supposed to have ten 250-watt lamps on a 20 amp circuit. The voltage is 120 volts to each lamp. Is this circuit adequate considering that the load is continuous and the
circuit can only be loaded to 80% of its rating? (You will see the calculation once you submit)
a Yes
b. No

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

Atank with constant volume contains 2.27 kg of a mixture of water phases (liquid-vapor). in the initial state the temperature and the quality are 127 °c and 0.6, respectively. the mixture is heated until the temperature of 160 oc is reached. illustrate the process in a t-v diagram. then, determine (1) the mass of the vapor in kg at the initial state, (2) the final pressure in kpa.

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.
