1. BASIC EQUATIONS

The following basic equations apply to air distribution with regard to flow rate, air heat transfer, liquid heat transfer.

(A) AIR FLOW

(1) Q = V × A where Q = flow rate, m3/s (cfm) V = velocity, m/s (fpm) A = area, m2(ft2)

(B) HEAT TRANSFER FOR AIR

(2) q = Q × p × csp × Dt where q = heat transfer rate, = Watts (BTU/hr) Q = flow rate, m3/s (ft3/hr) p = density kg/m3 (lbs/ft3) csp = specific heat J/kg°C (BTU/lb°F) Dt = temp. diff. °C (°F)

For Imperial Units this equation simplifies to:

(3) q = 1.08 × cfm × Dt

(C) HEAT TRANSFER FOR WATER

(4) q = Q × csp × Dt where q = heat transfer rate, = Watts (BTU/hr) Q = flow rate, kg/sec (lbs/hr) csp = specific heat J/kg°C (BTU/lb°F) Dt = temp. diff. °C (°F)

For Imperial Units with U.S. gpm, this equation simplifies to:

(5) BTU/hr = gpm × 500 × Dt

NOTE: In Si units, in equations (2) & (4), a unit analysis shows that the heat transfer rate simplifies to Joules per sec., and by definition, 1 Joule per sec. = 1 watt.

2. TEMPERATURE

1. To convert from degree Fahrenheit to degree Celsius, subtract 32 and divide by 1.8.

2. To convert from degree Celsius to degree Fahrenheit, multiply by 1.8 and add 32.

3. To convert from degree Fahrenheit to kelvin, add 459.67 and divide by 1.8.

4. To convert from kelvin to degree Fahrenheit, multiply by 1.8 and subtract 459.67.

5. To convert from degree Celsius to Kelvin, add 273.15.

6. To convert from kelvin to degree Celsius, subtract 273.15.

7. To convert from degree Rankin to Kelvin, divide by 1.8.

ISO METRIC AND UNIFIED SCREW THREAD DESIGNATIONSUnified screw threads are designated by nominal size and number of threads per inch. As an example, 3/4 – 10 UNC is a standard Unified screw thread having a nominal size of 3/4 inches and 10 threads per inch. To convert a Unified screw thread designation to an ISO Metric screw thread designation multiply nominal size by 25.4 and multiply the reciprocal of threads per inch by 25.4 to determine basic diameter in millimeters and pitch in millimeters. By doing so, 3/4 – 10 UNC converted to ISO Metric becomes M 19.05 × 25.4.ISO Metric screw threads are designated by basic diameter and thread pitch. As an example, M 8 × 1 is a standard ISO Metric screw thread having a basic diameter of 8 millimeters and a thread pitch of 1 millimeter. To convert an ISO Metric screw thread designation to a Unified (American) designation divide the basic diameter by 25.4 and multiply the reciprocal of the pitch by 25.4 to determine nominal size in inches and threads per inch. By doing so, M 8 × 1 becomes 0.315-25.4 UNS.
