1 lbm of carbon dioxide is heated in a constantpressure apparatus. Initially, the carbon dioxide is at 1000 psia and 200°F, and it is heated until its temperature becomes 800°F. Determine the final volume of the carbon dioxide, treating it as (a) an ideal gas and (b) a Benedict-Webb-Rubin gas.

Water is to be boiled at sea level in a 30-cm-diameter stainless steel pan placed on top of a 3-kW electric burner.If 51 percent of the heat generated by the burner is transferred to the water during boiling, determine the rate of evaporation of water. Please give your answer in kg/hour.

A piston-cylinder device initially contains 1 kg saturated liquid water at 220°C. Now heat is transferred to the water until the volume expands quadruple of its initial volume. Eventually, the cylinder contains saturated vapor only. Determine the volume at the final stage. (i) (ii) Determine the final temperature and pressure. (iii) Determine the internal energy change of the water. (iv) Sketch the T-v diagram and include all the related information.

A rigid tank contains 10 kg of water at 90°C. If 8 kg of the water is in the liquid form and the rest is in the Vapour form, determine (a) the pressure in the tank and (b) the volume of the tank.
