Water at 150°F flows in a straight 0.863-in diameter iron pipe (e = 0.00015 ft) between points A and B 350 ft apart. At A the elevation of the pipe is 112.0 ft and the pressure is 8.35 psi. At B the elevation of the pipe is 105.0 ft and the pressure is 8.80 psi. Compute the flow rate as accurately as you can.

The sum of the normal stresses does not change as the stress state rotates through an angle. 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
