Assume specific weight and velocity remains constant along the pipe Air is compressed from Determine the theoretical work of the compressor and the heat absorbed by the intercoolers.
The air handled is 0. If the compression is isentropic,find: a Piston displacement per cycle 0. Clearance is 5. A single stage reciprocating air compressor has two double acting cylinders each 46 cm diameter and 36 cm stroke and the piston rods are 50 mm in diameter. An air pollution control device requires 0. When tested under these conditions, performance was within the terms of guarantee. A 2-stage, double acting air compressor, mm x mm bore x mm stroke, running at RPM, has a free air unloader at each end for capacity control.
It is driven by a HP electric motor, volts, 3 phase, 60 Hz, RPM thru superhigh capacity V-belts at sea level installation. Suction pressure is 1. Safety precautions limit the temperature of the air in the HP cylinder to be 28 C below the flash point of the oil. Assuming perfect intercoooling, what would be the allowable working pressure of this compressor if the compression curve follows PV1.
An industrial plant requires Two steam engine driven three stage air compressor has to compress the under the following conditions: Intercooler pressure between 1st and 2nd stage — KPa Barometer reading — Determine the percent clearance of a single cylinder, double acting air compressor with bore and stroke of 45 cm x 45 cm x RPM.
The compressor is tested and it delivers air from The air is warmed to 38 C during the intake stroke. A two stage, reciprocating air compressor is required to deliver 0. The air enters the HP cylinder at 37 C. The intercooler is water cooled, with the water entering at 22 C and leaving at 32 C. Take free air conditions to be the same as suction conditions and for perfect intercooling, Calculate: a piston areas for minimum power 0.
Find the indicated power of a compressor delivering NH3 at 2. A 2 cylinder, single acting air compressor is directly coupled to an electric motor running at RPM. A closed metal tank is designed to be safe when subjected to an internal pressure of KPa. The discharge pressure is KPa and there is a 20 KPa pressure drop through the discharge valves.
Not counting frictional losses , Find: a the power require to operate the compressor if; 1. An air compressor is direct connected to a heat engine. The compressor handles Determine the percent clearance of a single cylinder, double acting air compressor with bore and stroke of 45 cm x 45 cm by 3 RPS. The air is warmed to K during the intake stroke.
Determine: a the theoretical and actual volumetric efficiency A reciprocating, 2-stage, single acting air compressor has a rated capacity of 0. The compressor has two LP cylinders each 13 cm diameter and one HP cylinder 7 cm in diameter; piston stroke is 10 cm. A two stage air compressor receives 0. All clearances are 3. A natural pipeline distributes gas through the country, pumped by a large gas-turbine driven centrifugal compressors.
Assume that the natural gas is methane, the pipe diameter is0. The compression process is isentropic and the discharge pressure is KPa. Determine: a the discharge temperature A 2 stage, double acting air compressor, operates at RPM.
The LP cylinder with a bore and stroke of The air in the intercooler suffers a
