Theoretical flow rate formula
WebbMathematically the discharge coefficient may be related to the mass flow rate of a fluid through a straight tube of constant cross-sectional area through the following: C d = m ˙ … Webb27 aug. 2014 · The flow rate usually is an average rate. Flow time: The amount of time a flow unit spends in a business process from beginning to end, also known as the total processing time. If there is more than one path through the process, the flow time is equivalent to the length of the longest path.

WebbThe relevant formula is: Q₁/Q₂ = (D₁/D₂) Where Q = flow rate, D = impeller diameter, 1 = current or before, and 2 = new or after For example, assume that you wanted to calculate … WebbAnalysis of the flow line in Figure 1 shows that the water flow has diffluent rates in the horizontal and vertical directions and belongs to the plane two-dimensional flow. If the Dupuit assumption can be introduced and the vertical diffluent rate is neglected, the calculation can be simplified to a one-dimensional flow calculation in the x direction [ 32 ].
