I saw Alex Matveeff posting on here. Would you get in touch with me?
I'm evaluating between AutoPIPE, CAEPIPE and PASS to determine what's most user friendly. I'm new to this pipe stress but am tired of waiting on consultants.
I have also emailed your software company.
Here's a problem I have at work and I was hoping someone could help me out. I haven't had to do a serious heat transfer problem since college.
A stability chamber that maintains a constant 104F 80% RH room has sprinklers serving it.
The 1" sprinkler pipe extends down into the room by about...
Anyone know where I can get information on the degree days for Moscow, Russia?
I've tried googling it but have not found anything yet.
I'd like to run dry coolers for free cooling and I'd like to get an idea of how mnay months that would work for me.
I have a few questions on gas pipe sizing and pressure drop.
The total load is 20,000 CFH with an equivalent length of 400 feet, gas pressure is 14" W.C. and minimum operating pressure for the equipment is 10" W.C.
Using the formulae for gas pressure I find that with 0.5" W.C. drop, I would use...
I am trying to figure out what the heat gain would be for a 250kVA transformer.
I have done several searches here and thru google and have not found corroborating info on the calculation.
One site calculates the heat gain as:
Heq = PeqK1K2 (W)
where
Heq = heat transferred from electrical...
I was wondering if someone would be able to suggest reference books/guides on how to design HVAC for a 6 story animal lab building. What codes and standards would apply?
Thanks for any responses.
Hello everyone. Can someone help me by directing me to a reference for air changes for large warehouses?
A typical warehouse would be 500,000 square feet and 30 feet high with many dock doors.
I have tried calculating the infiltration using the crack method but I read somewhere that for larger...
Anyone have an updated method of calculating infiltration based on Ashrae studies?
I have posted a similar thread in the HVAC forum.
I am revising my infiltration calcs for a metal building complete with dock doors and louvers. I have been using 25cfm/lf for crack infiltration per dock door and...
I am interested in researching air conditioning units that account for high sensible, low latent cooling.
Does anyone out there know of any major companies that deal with this issue? Energy recovery wheels or heat pipes are not an option since outside air is not usually available.
Thanks for...
I am looking for an application that will do heating and cooling calculations and be able to suggest the best system to cool/heat the space.
Whether it be DX systems or a chiller system. Does anyone know a program having these properties?
I have been told by the rep of a large propane supplier that propane pressure going into a building is usually less than 1lb. Well the tables provided in NFPA show sizing with either 10psi or less than 1lb. I just wanted to know how to go about sizing propane. If you have a 10 million BTU/h...
