Condensate discharge

0.4 lb/hr

Pressure differential

100 psi

Orifice area

0.0123 in²

Daily discharge

8 lb/day

Formula and working

W = 2.24 × d² × √ΔP (lb/hr, approx for water at saturation)

  1. 1

    Collect the inputs

    Orifice diameter = 0.125 in; Upstream pressure = 100 psig; Downstream pressure = 0 psig

  2. 2

    Apply the formula

    W = 2.24 × d² × √ΔP (lb/hr, approx for water at saturation)

  3. 3

    Result

    Condensate discharge = 0.4 lb/hr
