To calculate the flow rate in a cylindrical pipe, the basic formula, which is flow rate is equivalent to pipe cross-sectional area multiplied by velocity, can be used. Here the area is calculated as pi times pipe diamete... More »

To calculate the water flow rate through a given pipe size, multiply the area of the inner cross-section of the pipe by the velocity of the water. The velocity of the water is required for this calculation. More »

Pounds per hour (lb/hr) is a mass flow rate, whereas standard cubic feet per hour (SCFH) is a volumetric flow rate measured at a specific temperature and pressure. Therefore, the density of the fluid being measured as we... More »

To measure volumetric flow rate, use a flow meter. Cubic feet is a unit of volume, and minute is a unit of time. The rate of volume flow is referred to as volumetric flow rate. More » Science Measurements
