Commissioning an AHU

[frank]

So Frank marcs boss forgot to put the specific heat capacity of the air in his formula q= m x CP x p x dT where cp is the specific heat capacity ( 1.005) you say this is for air at 20oC , how does this figure change in relation to air temp .eg if I was working in a cold room when the air was 10oC ?

Google Specific Heat of Air and there are numerous tables which show the details you ask for
