Vacuum Pump Capacity Calculation Xls Jun 2026

Lucas realized the trap. If the air partial pressure is 30 mbar, and the leakage is 10 kg/hr. Density of air at 30 mbar is roughly $0.03 , kg/m^3$. Volume load from leakage = $10 / 0.03 = 333 m^3/hr$. Capacity of pump = $510 m^3/hr$. Available capacity for pump-down = $510 - 333 = 177 m^3/hr$.

"It’s a ratio," Lucas realized. "The volume of vapor is proportional to the ratio of pressures." Lucas realized the trap

"Exactly," Elias slapped Lucas on the back. "Now, calculate the time with the net capacity." Volume load from leakage = $10 / 0

"It's not just about the pump being 'big enough'," Elias concluded. "It's about the balance between the vessel volume, the air leaks, the water temperature, and the seal water temperature. Your spreadsheet tells us that this rusty 600 m3 pump can do the job, provided we don't have a sudden gasket blowout and we throttle the inlet to manage the flash steam."

Formula: [ S_req = \fracVt \times \ln\left(\fracP_startP_target\right) ]
