In this part, design a simple combinational circuit so that the value of the 4-bit switch input, SW[3] – SW[0], is displayed in decimal on HEX[1] and HEX[0]. Thus, your display will show the values 00, 01, 02, … 09, 10, 11, 12, 13, 14, 15 depending on the positions of SW[3]–SW[0]. The other 7-segment displays (HEX5-HEX2) must be off.

An engine runs on the ideal diesel cycle. the cycle has a compression ratio of 20 and a cutoff ratio of 2. the highest temperature in the cycle is 1200 k. if the heat into the system is 300 kj/kg of working fluid and using variable specific heats determine the work produced per mass of working fluid

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.
