Calculate the free air flow requirements for the following applications: 1. A 2 inch bore cylinder with a 10 inch stroke extends in 0.5 seconds when supplied with 83 PSIG air. The compressor intake temp is 47F and atmospheric pressure is 14.4 PSIA. The temperature at the cylinder is 79F 2. A 125mm bore cylinder with 20mm stroke and a 40mm piston rod retracts in 0.9 seconds when supplied with 8 bark air at 27C. Intake conditions are 0.9 bara and 13C Calculate the Cv factor for the following applications: 3 The flow required at the cylinder is 70 scfm and the temperature is that of standard air. The pressure drop through the valve is 4 psi and the inlet pressure at the valve is 86 psig. 4 Required flow is 1000 normal litres per minute and the temperature at the valve inlet is 32C. The valve inlet pressure is 6 ban, and the pressure drop through the valve is 0.2 bar. 5 The pressure at the inlet of the valve is 94 psig and the temperature is 83F. The cylinder is a 2" bore x 9" stroke and thrusts with a force of 283 lbs. The time to extend is 0.5 seconds. Hint: the pressure required to produce the cylinder thrust is the valve outlet pressure
