When using metric units, what constant do you use instead of 1.08?

When using metric units, what constant do you use instead of 1.08?

When using metric units, what constant do you use instead of 1.08?

(OP)
I'm updating some calcs to metric units and for the equation Q=1.08*cfm*delta T, and I don't have access to any air density and specific heat values in metric units.  Can someone help me out?

RE: When using metric units, what constant do you use instead of 1.08?

Q(W) = 1.23 x V(L/s) x dT (K) at sea level.

Density of air is reciprocal of specific volume, which you can easily get from a psychro chart.

RE: When using metric units, what constant do you use instead of 1.08?

a real anal point is that specific volume tells you the volume of moist air, that holds a unit mass of dry air, plus a small mass of water vapour.

Take the "V" out of HVAC and you are left with a HAC(k) job.

another question referring to using degrees celsius....

When using bin data in degrees C, is there a standard way to evenly space out the temps? (e.g w/bin data for deg F, there are usually 2.5-5 deg between each temperature)
