I seem to be having a fine time calculating bolts tightening torque value for the following situation:
A 1000 lbs rectangular box sits on two rubber pads of 1" thick and 4" wide x 18" long at the ends of box.
There are (4) 1/2" bolts (2 each end) that need to be tightened, but the max allowed...
Hi there!
Would some one give me a hint on how to tackle this issue?
Have a skid of about 40' long that is supported on 14 (7 each side) vibration isolators. The supported unit weighs about 130,000 lbs. Isolators have equal space through out the skid length. CG is at 15' from the left.

Hi there!
I am at loss, need helpful hints.
I need to calculate pressure loss thru a 30" ID formed tubing miter cut and welded together to form a 45° & a 90° elbows. 90° has two miter cuts. 30" leg length.
Looking at Crane data book I see that for alpha=45° =15fT, and for alpha=90° K=60fT.
OK...
Hi all,
If I have this Co-Gen unit that can generate enough hot water to power a 600 ton absorbtion chiller and the system runs about 8000 hours a year, then what would equivalent "ton-hours" of electric cooling be?
I am guessing it would be 600 * 8000 = 4,800,000 ton-hour of electric cooling...
Hello everyone.
Is there an easy way to calculate 22" exhaust pipe internal pressure caused by a backfire after the turbo?
Let's say the fuel is digester gas with 60% methane.
The system is a gas engine/generator set rated 2100 KW.
Thanks in advance!
