Ft.) BTU/Hr = 2.0 x DT x A HEAT IN HYDRAULIC OIL Due to System Inefficiency (SG=.89-.92) Heat (BTU/Hr) = Flow Rate (GPM) x 210 x Temp. Difference (F ) BTU/Hr = Q x 210 x DT HEAT IN FRESH WATER Heat (BTU/Hr) = Flow Rate (GPM) x 500 x Temp. Difference (F ) BTU/Hr = Q x 500 x DT Note: One British Thermal Unit (BTU) is the amount of heat required to raise the temperature of one pound of water one degree Fahrenheit. One Horsepower = 2545 BTU/Hr. Accumulator Formulas Formula For: Word Formula: Letter Formula: PRESSURE OR VOLUME With Constant T (Temperature) Original Pressure x Original Volume = Final Pressure x Final Volume P 1 V 1 = P 2 V 2 Isothermic PRESSURE OR TEMPERATURE With Constant V (Volume) Original Pressure x Final Temp. = Final Pressure x Original Temp. P 1 T 2 = P 2 T 1 Isochoric VOLUME OR TEMPERATURE With Constant P (Pressure) Original Volume x Final Temp. = Final Volume x Original Temp. V 1 T 2 = V 2 T 1 Isobaric PRESSURE OR VOLUME With Temp. Change Due to Heat of Compression Original Press. x Original Volume n = Final Press. x Final Volume n P 1 V 1 n =P 2 V 2 n Final Temp./Orig. Temp. = (Orig. Vol./Final Vol.) n-1 = (Final Press./Orig. Press.) (n-1)/n T 2 /T 1 =(V 1 /V 2 ) n-1 = (P 2 /P 1 ) (n-1)/n Volume and Capacity Equivalents Cubic Inches Cubic Feet Cubic Centimeters Liters U.S. Gallons Imperial Gallons Water at Max Density Pounds of Water Kilograms of Water Cubic Inches 1 0.0005787 16.384 0.016384 0.004329 0.0036065 0.361275 0.0163872 Cubic Feet 1728 1 0.037037 28.317 7.48052 6.23210 62.4283 28.3170 Cubic Centimeters 0.0610 0.0000353 1 0.001 0.000264 0.000220 0.002205 0.0001 Liters 61.0234 0.0353145 0.001308 1 0.264170 0.220083 2.20462 1 U.S. Gallons 231 0.133681 0.004951 3.78543 1 0.833111 8.34545 3.78543 Imperial Gallons 277.274 0.160459 0.0059429 4.54374 1.20032 1 10.0172 4.54373 Pounds of Water 27.6798 0.0160184 0.0005929 0.453592 0.119825 0.0998281 1 0.453593 Fluid Power Formulas
