WebThe formula for the flow velocity of a fluid in a pipe is: v = Q / A. v is the velocity of the fluid, in meters per second (m/s). Q is the volumetric flow rate, in cubic meters per second (m^3/s). A is the cross-sectional area of the pipe, in square meters (m^2). This equation states that the flow velocity is proportional to the flow rate and inversely proportional to … Web1. If the head loss and pressure drop is given then we find volumetric flow rate or mass flow rate. 2. Now if mass flow rate and pressure drop is given, in this case we easily can determine head loss. 3. And at the last case mass flow rate and head loss given, then pressure drop also can be determine.
