Ammonia is used in liquid form for a process and is needed at a temperature of 15°c. it is available at 0°c. liquid carbon dioxide is used rather than water as a heat source (using water may lead to trouble). liquid carbon dioxide is available at 5°c and a mass flow rate of 1.25 kg/s. a 15-m-long double pipe heat exchanger, made of 21/2 x 11/4 type k copper tubing, is available for this service. for an ammonia flow rate of 1.2 kg/s, calculate outlet temperatures and pressure drops. will this setup work?

Apiston-cylinder with a volume of 0.25 m3 holds 1 kg of air (r 0.287 k/kgk) at a temperature of 100 c. heat transfer to the cylinder causes an isothermal expansion of the piston until the volume triples. how much heat is added to the piston-cylinder?

An air conditioning system consist of a 5 cm diameter pipe, operating at a pressure of 200 kpa. the air initially enters the pipe at 15°c with a velocity of 20 m/s and relative humidity of 80%. if the heat supply throughout the process is 960 w, determine the relative humidity and the temperature at the outlet

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10
