This is a parallel question regarding the "static electric discharge hazard " thread
The thread is quite interesting and has provided me some good information on the subjet. I am curently desining the fuel system, including the day tank, for a mobile diesel genset (approx 100gal/400l).
I...
This question might seem lame but I want to know if it is at all possible, for a 1 inch grade 8 bolt torqued at only 200 ft*pound (very little preload) secured with a cutter pin, could come loose ?
This is to secure diesel engine mounts on a skid base. So the joint will be exposed to engine...
"ADMINISTRATION KILLS ENGINEERING"
I am rigidly mounting a diesel engine with a through hole/slot that is connected to a rigid solid skid base.I am using 1 inch grade 8, coarse tread, zink plated shoulder bolts,washers at both ends and nuts have a nylon lock to help prevent loosening because of...
"ADMINISTRATION KILLS ENGINEERING"
Here it is
I am designing a 2.7Mw mobile genset. The engine is a MTU 20v4000 that has four(4) mounts that are attached to a skid base.
The installation specs require that mounting must be permissive to thermal expansion

I am desperatly trying to establish a good ball-park figure for the value of convection coefficient h in a forced air flow (fan) condition. This will be used to determine heat regection of an exhaust system inside a trailer(enclosure).
I understand that h~10 is a rule of thumb for natural...
I am trying to establish the energy (watts) dissipated by an exhaust system. This is to determine the air flow needed to dissipate that heat from an enclosure. I want to considre only the forced convection effects by using the formula:
Q(W)=h* area * (Tsurface - Tambiant)
where h is the...
