Calculate throttling diameter The calculations below must only be used to obtain estimates. The calculations apply to short throttlings, where the diameter > the length of the constriction. A value of 0.86 kg/dm3 has been used for oil density. Separate decimals with a decimal point. Required input is missing! Flow = l/min Pressure drop = bar RESULT Throttling diameter = mm PMC Group AB accepts no liability for the consequences that any errors in formulas and software may have! © PMC Group AB 2012
