Hello,
Can a North American fabricator which is a ASME U stamp holder get all phases of fabrication/testing (except hydrotest and name plate rubbing) done overseas and apply U stamp in its shop?
What are the min. requirements of ASME from the overseas fabricator?
Thanks!
Hello,
I need to fix an existing design for building/room pressurization.
Here is the current design:
A one storey building with a large room, a small room and a mechanical room. An outdoor filtration unit with a constant volume supply fan and preheat coil supplies OA. An indoor AHU with a...
Hello,
There is a process plant with some pumps pumping fluid out of the plant
I use 2545*P*((1-eff)/eff).FUM.FLM classic pump motor heat dissipation formula from ASHRAE fundamentals handbook for these.
Now there are a lot of other pumps in this plant which only carry fluid between H/Xs...
Hi,
There is a process building which has the following system:
1)AHU with a supply fan, modulating outdoor and return dampers, no coils (heating by unit heaters and free cooling)
2)Relief dampers which will open at 0.1" with respect to outdoors for AHU
3)Exhaust fans to help cooling when...
Hi,
There is an unoccupied pumphouse with 1500 hp+ motors in it located in a climate with -40 F winter design conditions. Because there is so much internal heat gain from pumps and piping, this building requires cooling even when it is -40 F outside. Inside design conditions are 95F and 60% RH...
Hi, we have vav boxes with reheat and convectors at perimeter zones. Convectors are sized to offset envelope loss. Vav reheat valves are not commanded open before room temperature drops below set point (vav boxes set to min flow), and we have reheat valves 100% open when room temperature is 3...
My boss argues that ALL the power drawn by a computer will end up as heat gain in a room. I know that energy needs to be conserved (1st law of thermo.)
My questions:
1-How does ALL the power drawn to rotate a hard disk or an inserted CD (Rotational power=Torque X rotational speed) end up as...
