. A single stage double acting air compressor delivers 5 m of free air per minute at 1 bar and 20 C to 7.5 bar with the following data;R.P.M. = 300; Temperature rise of air during suction stroke = 12 C ; Clearance volume = 5% of stroke volume; Index of compression and expansion, n=1.3; Length of the stroke = 1.3 times the cylinder diameter.

Calculate: 1. Power input to the shaft; 2. The volumetric efficiency; and 3. The cylinder diameter

An adult inhales approximately 12 times per minute, taking in about 500 mL of air with each inhalation. Oxygen and carbon dioxide are exchanged in the lungs, but there is essentially no exchange of nitrogen. The exhaled air has a mole fraction of nitrogen of 0.75 and is saturated with water vapor at body temperature, 37°C. If ambient conditions Professor Christina Tang, [email protected] 2 are 25°C, 1 atm and 50% relative humidity, determine what volume of liquid water (mL) would...

The velocity of steam leaving the nozzle of a single-stage impulse turbine is 813 m/sec. The nozzle angle is 20° and the blade speed corresponds to maximum blade efficiency. The moving blade is symmetric, assumed to be frictionless, and there is neither expansion nor contraction of the steam flow through the blade passage. Draw the velocity diagram and determine the relative velocity of steam leaving the blade.
