A steady flow, steady state air compressor with a surface temperature of 80.0°F handles 4000. ft3 /min measured at the intake state of 14.1 psia, 30.0°F and a velocity of 70.0 ft/s. The discharge is at 45.0 psia and has a velocity of 280. ft/s. Both the inlet and exit stations are located 4.00 ft above the floor.
Determine the discharge temperature and the power required to drive the compressor for
a. A reversible adiabatic process.
b. An irreversible adiabatic process with a compressor work transport efficiency of 80.0%.

ii. Derive a relationship between time t and the velocity V. iii. Derive a relationship between displacement D and the velocity V.
A football official inflates a football to the required gauge pressure of 13 psi prior to a game. The football has an internal volume of 160in^3 and the air is at a temperature of 75 degrees F when the football is first inflated.
determine the minimum no of teeth required on pinion in order to avoid interference which is to gear with 1 a wheel to
carbon dioxide at 20 degrees celsius and a pressure of 550 kpa flows through a pipe at 0.04 ns what would be the
A volume fraction f = 0.2 of silicon carbide (SiC) particles is combined with an aluminium matrix to make a metal matrix composite. The modulus of particle reinforced composites lies very close to the lower bound of Young's modulus for a composite.
You own an aluminium processing plant, and want to hot roll aluminium from a billet to a sheet form. The billet is 5m long, 3m wide and 0.25m thick. Your output sheet is to be 0.001m in thickness by 3m width. You configured your plant as a flexible m..
A ball is dropped from a height of 1.0m, bounces off the floor and is observed to rise up a maximum height of .8 m. How high will the ball rise after its second bunch?
An initially empty, well insulated, rigid tank with a volume of 2 m3 is fitted with a mixing device. The tank has two inlets and zero outlets. One inlet is water at 1.07 MPa and 630oC while the other is saturated liquid water. Both enter the tank slo..
An 80-lb weight falls through 5 ft and is then caught at the end of a wire rope 90 ft long having a cross-sectional area of 0.5 in.2. Find the maximum dynamic stress in the rope, assuming E = 15 × 106 psi.
A 200mm DN pipeline has to deliver 80ml/h of water at a discharge pressure of 5,550kPa. Approximately how many pump stations would be needed for a pipeline 300km long?
