# Flow Coefficient of Liquid (Water) Calculator

The flow coefficient of a gadget is a relative measure of its proficiency at permitting liquid flow (flow expressed by weight). Obtain the flow coefficient (Cv) of water based on the water flow, specific gravity and pressure drop in weight.

#### Formula:

##### Flow is Expressed by Weight

C_{vw} = w / (500 * (SG * dp)^{1/2})
C_{vi} = (5.8 * w) / (500 * (SG * dp)^{1/2})
**Where,**
C_{vw} = Flow Coefficient in Liquids (Imperial Unit)
C_{vi} = Flow Coefficient in Liquids (SI Unit)
w = Water Flow
SG = Specific Gravity
dp = Pressure Drop
