WebThe volume flow rate Q Q of a fluid is defined to be the volume of fluid that is passing through a given cross sectional area per unit time. The term cross sectional area is just a fancy term often used to describe the area through which something is flowing, e.g., the circular area inside the dashed line in the diagram below. WebSolved Examples for Mass Flow Rate Formula. Q.1: A fluid is moving through a tube at a speed of 20 meters per second. The tube has a transverse area of 0.3 square meters. The density of the fluid is given as \rho = 1.5 grams per cubic meter. Determine the amount of mass flowing through the tube using Mass Flow Rate Formula.

In a nozzle or other constriction, the discharge coefficient (also known as coefficient of discharge or efflux coefficient) is the ratio of the actual discharge to the ideal discharge, i.e., the ratio of the mass flow rate at the discharge end of the nozzle to that of an ideal nozzle which expands an identical working fluid from the same initial conditions to the same exit pressures. Mathematically the discharge coefficient may be related to the mass flow rate of a fluid through …
