![]() ![]() At a utility scale, energy generated during periods of low demand can be released during peak load periods. Increasing the pressure p 1 will not increase the velocity of escaping air beyond this limiting velocity unless a special converging diverging nozzle design is used rather than an orifice. A pressurized air tank used to start a diesel generator set in Paris Metro Compressed-air energy storage (CAES) is a way to store energy for later use using compressed air. In applying the above equation, when the ratio p 2/p 1 approximately equals 0.53, under normal temperature conditions at sea level, the escape velocity v 2 will be equal to the velocity of sound. P 1 = Pressure of air in container, pounds per square inch (psi). P 2 = Atmospheric pressure = 14.7 pounds per square inch (14.7 lbs/in 2) K = 1.41 for adiabatic expansion or compression of air G = Acceleration due to gravity, 32.16 feet per second squared (32.16 ft/sec 2) V 2 = Velocity of escaping air in feet per second (ft/sec) ![]() Since the change takes place almost instantly, little heat can escape from the fluid and the flow may be assumed to be adiabatic.įor a large container with a small orifice or hole from which the air escapes, the velocity of escape (theoretical) may be calculated from the formula: Third, using air to clean forces the dirt and dust particles into the air, making these contaminants airborne and creating a respiratory hazard. If air, or gas, flows from one chamber to another, as from a chamber or tank through an orifice or nozzle into the open air, large changes in velocity may take place due to the difference in pressures.
