How do you calculate flow coefficient?
SG is the specific gravity of the fluid (for water = 1), P is the pressure drop across the valve (expressed in psi). In more practical terms, the flow coefficient Cv is the volume (in US gallons) of water at 60 F that will flow per minute through a valve with a pressure drop of 1 psi across the valve.
How do you calculate kv?
The value of Kv can be calculated according to the values given, such as: flow, Pressure drop and data of the operating conditions of the installation….Q = Actual flow rate in m3/h at the temperature x.r = Density of the water in kg/dm3 (depends on the temperature)DP = Pressure drop through the valve in bar.
Does higher kV mean faster motor?
Generally speaking the more Kv a motor has, the more RPM and more power. For example, a 9000Kv motor would be faster than a 2200Kv motor. A higher turn number means more wire and thus more resistance, resulting in a slower motor. So turns with a lower number means a faster motor.
Is KVS better than DPS?
The students of DPS are given all round knowledge. Discipline of DPS is far better than Kv. K.V is the best school for children however D.P.S is the other option.
