A two stage, single-acting compressor has a free air delivery of 4.2 m3/min when the ambient condition is 1.013 bar, 15oC.
• The suction pressure and temperature are 0.98 bar and 32oC respectively. • The air is compressed to 16 bar according to the law pv1.3 = C.
Assuming that the compressor is designed for minimum work with complete intercooling, calculate the indicated power required to drive the compressor.

A single stage double acting air compressor having a clearance of 4% takes in air at 14.2 Psia and 60 and compresses it to 200 Psia. If the weight of the air compressed per minute is 50 lbs. and n = 1.35, compute: a) The work required to compress the air per minute b) The piston displacement if the compressor operates at 100 RPM c) The volume of free air measured at 14.7 Psia atmospheric pressure.

1) A reciprocating compressor has two stages with inlet air going into LP stage at 1 bar, 16°C and at the rate of 12 m3/min. Air is finally delivered at 7 bar and there is perfect intercooling at optimum pressure between the stages. The index for compression is 1.25 and compressor runs at 600 rpm. Neglecting clearance volume determine intermediate pressure and total power required. 2) A reciprocating compressor of single stage and double acting type has free air delivered...

A single-tooth hardened-steel worm has a catalog rating of 2000 W at 600 rev/min when meshed with a 48-tooth cast-iron gear. The axial pitch of the worm is 25 mm, the normal pressure angle is 14.5°, the pitch diameter of the worm is 100 mm, and the face widths of the worm and gear are, respectively, 100 mm and 50 mm. Determine the three components of the load on the worm.

A single post-synaptic neuron has two axon terminals synapsing with it. When only the first terminal releases transmitter, the post-synaptic neuron fires an action potential. However, when both terminals fire simultaneously, the post-synaptic neuron does not fire an action potential. How can you explain this?
