Question 4 A steel rod of 20 mm diameter passes centrally through a copper tube of 50 mm external diameter
and 40 mm internal diameter. The tube is closed at each end by rigid plates of negligible thickness.
The nuts are tightened lightly home on the projecting parts of the rod. If the temperature of the
assembly is raised by 50°C, calculate the stresses developed in copper and steel. Take E for steel
and copper as 200 GN/m² and 100 GN/m² and α for steel and copper as 12x 10-6
per °C and 18 x
10-6
per °C

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.
