You need approximately 30-35 BTUs/hour for each square foot of space if you live in a warm climate and 50-60 if you live in a cooler climate. The online tool is used to calculate BTU (British Thermal Unit) requirements for room air conditioners. Power Load Calculator. This allows 100% of the rated air conditioning capacity to be utilized and maximizes efficien-cy. The lung capacity calculator finds it by adding the Inspiratory Reserve Volume, Tidal Volume, and Expiratory Reserve Volume:. The examples below show how there are three ways of doing this. A calculation professionally referred to in the Construction Industry as a Manual J based load analysis. How to calculate "breathe time" in a SCBA system? Hey guys, I am wondering how I can calculate the rough amount of time I would be able to breathe using a SCBA (self contained breathing apparatus) when I know both the psi capacity of a tank as well as the cubic centimeters of the tank. Please also refer to the Psychometric Chart for various values referenced. What is the correct formula to calculate functional residual capacity (FRC)? Functional residual capacity (FRC) is the volume that remains in the lungs after a single quiet breath. unit capacity = total capacity NOT sensible capacity (rated @ 95F ambient, 80F edb, 67F ewb) sensible cooling capacity 70-80% of total latent capacity provided >what is needed on West coast gross capacity does NOT include deduction for fan heat EER (Energy Efficiency Ratio)= btu/hr output KW input. This value, usually around 4 to 8, divided into your cooling capacity (preferably in kW), will give the electrical power consumption of the unit when running. You can derive a chiller's capacity from the temperature drop it creates and the volumetric flow of the water within it. Click on the "Lock DP" box to enter a new temperature at the same dew point. Air compressors for the home or small shop have been advertised and sold with ridiculously inflated horsepower ratings. We think this is a good deal. So 927000 J = 927000 X 2.
