WebThe above equations calculate the steady state mass flow rate for the pressure and temperature existing in the upstream pressure source. ... In the case of upstream air pressure at atmospheric pressure and vacuum conditions downstream of an orifice, both the air velocity and the mass flow rate becomes choked or limited when sonic velocity … WebCalculate air velocity, metres/second from pressure difference (Pitot) The standard air density at 20°C and 1013mb barometric pressure is 1.2 kg/m 3. Enter pressures and any different density value in the appropriate boxes. Total Pressure: Static Pressure: Air Density: Pa: Pa: kg/m 3 : Velocity = m/s
WebBernoulli’s Equation is used to determine fluid velocities through pressure measurements. It starts with qualifications of nonviscous, steady, incompressible flow at a constant temperature. P + ½ρv 2 + ρgy = constant P = pressure v = velocity ρ = density of the fluid g = gravity y = height WebUnder Pitot tube reading (velocity pressure, inches of water) read air velocity, feet per minute. Determining Volume Flow Once the average air velocity is know, the air flow rate in cubic feet per minute is easily computed using the formula: Q = AV Where: Q = Quantity of flow in cubic feet per minute.
