Online calculator to quickly determine Condensate Load From Heating Air. We have 8GPM of water with an inlet temperature of 65°F and outlet temperature of 95°F. BTU Calculator AC BTU Calculator. TUBE & COIL SIZING TECHNICAL BULLETIN TA-103A TFE and METAL QUICK ESTIMATION (BASED ON STEAM) HEAT-UP STEP 1 Determine gallons in tank. Assuming that the solution depth would never go below 4 feet, this coil would function properly. We can figure the same thing in the case of walls with oversized windows. Electric Heater Room Size Calculator. Using a 15V supply, the system pulls about 4.5A of current which is equivalent to 67.5W of heating power. Every building has them. Air is flowing at 187 CFM and 5 PSIG pressure.

This is important information as it helps determine how long the coil needs to be. The sensible heat in a heating or cooling process of air (heating or cooling capacity) can be calculated in SI-units ashs = cp ρ q dt (1)wherehs = sensible heat (kW)cp = specific heat of air (1.006 kJ/kg oC)ρ = density of air (1.202 kg/m3)q = air volume flow (m3/s)dt = temperature difference (oC)Or in Imperial units ashs = 1.08 q dt (1b)wherehs = sensible heat (Btu/hr)q = air volume flow (cfm, cubic feet per min… ÷ 144 Coil Air Velocity = CFM of Air ÷ Coil Square feet = Feet Per Minute Velocity (FPM) Selection Note: As you raise the air velocity, a coil will increase in capacity but will have a higher air resistance.
