    Pump up equation?

    Answer depends on what pressure the pump operates at. If less than 100psi, you can never fill the barrel. Of course you must have just over 100psi, otherwise the air would never have enough pressure to overcome the water pressure. Now assuming you have just enough pressure, with a 100cfpm pump...

    Bolt Torque using PCBolts

    No nuts involved, this is a flange that is bolted to a threaded adapter plate. Torque coefficient provided by PCbolts is .148. If I understand this correct, one should torque bolts to 2/3 of their yield strength and provide sufficient thread length to ensure set end is not stripped out. The...

    Bolt Torque using PCBolts

    Excuse me for not checking this first. PCBolts is a Dos based program developed for Naval Sea Systems Command(NAVSEA PMS390T) and is dated 1995. It may be available on Navy computer systems, but is probably not well known commercially. In view of this, I will revise my question to ask what is...

    Bolt Torque using PCBolts

    I have a problem involving determination of proper torque using 3/8-24UNF K-monel 100ksi YS bolts into a Monel 25K YS plate. It is generally desired that the externally threaded part will break before the external or internal threads slip. FED-STD-H28/2B accounts for this by ensuring adequate...
