Sensible heat load calculation

[pmc]

I'm having trouble locating the equation for sensible heat load within the MERM

qs=(1.08)(cfm)(dt)

I've seen this come up in a couple practice problems and would like to see how it's more or less derived but the MERM doesn't seem to mention it.

If you have MERM13, check out equation 40.18, and...

Bottom sentence on p. 40-8: "The constant 1.08 is the product of an air density of 0.075 lbm/ft^3, a specific heat of 0.24 Btu/lbm-F, and the factor 60 min/hr."

There it is. Thanks for your help.

Just so you're aware, I found the section on sensible heat load in a matter of about 10 seconds, by using the index.

Thanks I used the index too but missed the last sentence where it shows the 1.08 factor. However, I found it in 11 seconds, not 10. Always room for improvement
