Question

in measuring the diameter of the following rod reading were taken a different points along the lengths: 33 53 33 43 33 48 and 33.18mm find the average diameter of the rod

Answer 1

Answer:

kg. of air at a pressure of 875 kN/m² occupies a volume of 0.35 m². The

air is then expanded to a volume of 2 m3 at constant pressure. Find the

work done and heat transfer during the process. Take R = 0.287 kJ/kg K

and C = 0.717 kJ/kg K.

(W = 1443.75 kJ ; Q = 5050.5 kJ]
