WebHydro-static Pressure Calculation for Pressure Vessel: At least, Hydro-static Pressure = 1.3 x Maximum Allowable Working Pressure or MAWP. When Maximum Allowable Working Pressure or MAWP calculation is not done, then we used Design pressure in place of MAWP. Hydro-static Pressure = 1.3 x Design Pressure. WebDialing the pressure down by 25 psig, the plant could save 12.5 percent energy on an annual basis. To calculate the energy savings, use the energy equation below: BHP x .746 x # hours/year x \$/kWh . Motor Efficiency. Note that compressors are rated in hp, not kW. To calculate kW, multiply BHP by the constant (.746).
