Good afternoon;
Could someone assist me in verifying my calculation? Or point me in the right direction to a reasonable estimation?
I am attempting to work out a decent mathematical model for cooling round solid rods on a cooling bed. The material needs cooled from a high of 700*F to 150*F...
Could someone please verify my research on the use of bushings in fuel gas pipe?
My understanding from searching on Google is only malleable iron when reducing more than 1 size is acceptable. No Cast Iron.

We are looking at replacing a Cooling tower with Geothermal Cooling for a process water loop.
80KW total power usage.
10*F temp differential on cooling tower design
20*F temp design differential on system
operating pressure 30psi
If we move to geothermal cooling our temp differential will be...
We are going to a new gas main system. The existing system is 3" black pipe at 15" WG. I am looking at changing pressure from the existing 15" WG to 7" WG, 2psi or higher. I would like your opinions for 2 reasons; 1 I am studying for my PE and wish to know the "test" method for calculating this...
I am working on installing a simple hood with stack to draft the heat from a 1,000,000 BTU/HR furnace with a vertical escape and horizontal run. The unit uses a blower running ~7" WC. Furnace opening is ~3"x 36". My current plan is to use a simple rectangular sloped up hood attached to stove...
I am a little out of my realm. We are working on a late 70's induction brazing unit 40KW which has been blowing fuses. I have dealt with the primarily mechanical side and wish to move to the theory of operations. I have read through what literature I can find but am still left with questions...
I have been selected to take the PE next month and have selected the mechanical systems and materials for the afternoon. I waited 7 years before taking the FE and do not recall anything about the discussion of PE prep or suggested materials for the test during my college days.
I understand the...
