WebFlow In pipes under pressure or in open channels under the force of gravity, the volume of water flowing past any given point in the pipe or channel per unit time is called the flow rate or discharge (Q). In the U.S., flow rate may be expressed as cubic feet per second (ft3/s or cfs), gallons per minute (GPM), or million gallons per day (MGD). WebIf the cube of wood had a specific gravity of 0.6, 60% of the wood would be submerged beneath the water's surface. Ice has a density of about 920 kilograms per meter cubed. That means ice has a specific gravity of 0.92. And that's why 92% of an iceberg's volume is actually underneath the water. north cascades bank twisp waWebFeb 20, 2024 · Figure 12.1.1: Flow rate is the volume of fluid per unit time flowing past a point through the area A. re the shaded cylinder of fluid flows past point P in a uniform pipe in time t.
