How do you convert GPM?

Convert the volume of water (bucket’s capacity) to gallons. Divide the volume by the time expressed in seconds to get gallons per second. Multiply by 60 to get gallons per minute.

How do you calculate GPM in HVAC?

The GPM formula is GPM = Air side Btu ÷ (measured water Δt x 500).

#### What is the equation for CFM?

CFM = FPM x Duct Cross Sectional Area. Finding the Flow Velocity, typically expressed in feet per minute (FPM), is the first step in filling in our equation variables. To find the Flow Velocity, we use the equation: FPM = 4005 x √ΔP (The square root of the Velocity Pressure). Click to see full answer. Keeping this in consideration, what is
