Glycol Capacities and Correction Tables The charts, above, illustrate the differences between propylene based and ethylene based glycol. Since we recommend propylene based glycols because of their non-hazardous nature, we must be aware of the effects on the standard refrigeration heat exchangers and pumps.
GLYCOL CORRECTION FACTORS. Example: Pressure drop through the device is 5' with water at 50F. Using a 50% propylene glycol solution. From chart above, correction factor is 1.75. Multiply 5' x 1.75= 8.75' corrected pressure drop for 50%PG.
Propylene Glycol BTUH Correction Factors | Hydronic Systems
2019年9月23日 · If we take the specific gravity times the specific heat, we could call it a correction factor. GPM = BTUH / (GPM XΔT X 500 X CORRECTION FACTOR) The correction factor depends on the temperature of the fluid and the percentage of the fluid. We offer you the following chart of these correction factors.
2016年8月17日 · PRESSURE HEAD CORRECTION FACTOR FOR TEMPERATURES AND PROPYLENE GLYCOL Pressure head correction factor (multiplier) as a function of average fluid temperature (°F) and propylene glycol concentration (Volume %). Using the Chart: › Find the average water temperature to the left ›
FLOW CORRECTION FACTOR FOR TEMPERATURES AND PROPYLENE GLYCOL Flow correction factor (multiplier) as a function of average fluid temperature (°F) and propylene glycol concentration (Volume %). Using the Chart: › Find the average water temperature to the left › Move horizontally to the right until the intersection with actual glycol ...
Piping Pressure Drop Correction Factors when using Glycol - RL Deppmann
2019年10月14日 · Propylene Glycol Needs More Horsepower than Water. Glycol is heavier than water at this temperature. If I start by keeping the 267 GPM at 80 feet selection and change from water to 40% PG, there is a pump correction. It takes more horsepower to move the glycol than water. The water HP shown above is 7.21.
correction factor. GPM = BTUH / (GPM XΔT X 500 X CORRECTION FACTOR) The correction factor depends on the temperature of the fluid and the percentage of the fluid. We offer you the following chart of these correction factors.
