How do you calculate mass flow through a nozzle?
We can determine the value of the mass flow rate from the flow conditions. A units check gives area x length/time x time = area x length = volume. The mass m contained in this volume is simply density r times the volume. To determine the mass flow rate mdot, we divide the mass by the time.
How do you calculate nozzle discharge?
To work out the flow rate of water from a nozzle we need to work out the volume in a given period of time. To do this we work out the area of the nozzle and then multiply it by the velocity of the water coming from the nozzle to give us volume per unit of time.
How is flow orifice size calculated?
Divide the flow of the liquid by the velocity of the liquid to determine the area of the orifice in square feet. In the above example, you would divide 8 by 2. The total area of the orifice would be 4 square feet.
Is there a flow calculator for Venturi nozzles?
The calculator is not for pulsating flow, or non-steady flow when the flow rate is changing in time. This calculator also calculates total pressure drop created by the nozzle. You can use this calculator for all three types of nozzles covered in standards: ISA 1932 nozzle, long radius nozzle, and Venturi nozzle.
How is the flow rate of a nozzle calculated?
To calculate flow rate, you have to enter the nozzle inlet and throat diameter, together with fluid properties – density and viscosity. For a gas as flowing fluid, instead of the density, you can enter gas constant, pressure and temperature at actual conditions. Density is then calculated using an ideal gas state equation.
What is the Reynolds number in nozzle throat?
Reynolds number in nozzle throat (Red) resistance factor (K) Fluid properties temperature in nozzle inlet (T1) K°C°F inlet density (ρ1)
