Ten pounds of water at 35oF, and 6.00 lb of steam at 250oF and 20 psia are mixed together in a container of fixed volume. What is the final temperature of the mixture? How much steam condense? Assume that the volume of the vessel is constant with a value equal to the volume of the steam and that the vessel is insulated.

An insulated cylinder having an initial volume of 2 ft3 contains carbon dioxide at 15 psia and 440oF. The gas in then compressed to 200 psia in a reversible adiabatic process. Calculate the final temperature and the work (in Btu) involved during this process.

A wet cooling tower is to cool 25 kg/s of cooling water from 40 to 30°C, at a locationin which the atmospheric pressure is 96 kPa. Atmospheric air enters the tower at 20 °C and 70 percent relative humidity, and leaves saturated at 35 °C. Neglecting the power input to the fan, determine (a) the volumetric flow rate of air at the cooling tower inlet and (b) the mass flow rate of make-up water required.

A) Define the following: Pipes in series, Dehydration, Critical point, Condensate, Real gas B) A 50-cubic ft tank contains gas at 50 psia and 50F°. It is connected to another tank that contains gas at 25 psia and 50Fº When the valve between the two is opened, the pressure equalizes at 35 psia at 50F° as in the adjacent figure. ÉT What is the volume of the second tank? Tank-2 Tank-1
