(a) A bipolar transistor is biased in the forward-active mode. The collector current is iC = 726μA and the emitter current is iE = 732μA. Determine β, α, and iB. (b) Repeat part (a) if iC = 2.902 mA and iE = 2.961 mA

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

Apressure vessel with an r/t 20 cannot be treated as thin walled vessel. a)-trune b)- false

Acarnot refrigerator operates in a room in which the temperature is 21°c and of power when operating. if the food compartment of the refrigerator is consumes 3 kw to be maintained at 2°c, determine (a) the coefficient of performance of the cycle and (b) the rate of heat removal from the food compartment. refrigerator cycle that has a higher coefficient of performance than that of the discussed (e) is it possible to develop a carn ot refrigerator, operating between the same temperature limits? explain
