Future Copy

I going to upload an Excel spreadsheet for solenoid design based on Charles Underhill’s classic work “Solenoids Electromagnets & Electromagnetic Windings.” I haven’t finished the write up but I should be finished soon. By using Excel’s “Goal Seek” an optimum solution can be obtained. It’s trial method but doesn’t take too long to find a solution.

I just uploaded a copy of Crosby’s “Pressure Relief Safety Valve Handbook.” This is one that is hard to come by.
