Greenhouse Thermal Mass Water Calculator
Estimate water volume needed for a heat-storage target per degree. The form keeps the source measurements beside the calculated water volume per degree.
Enter values for water volume per degree
Read each Greenhouse Thermal Mass Water field note before calculating water volume per degree.
Arithmetic used for Greenhouse Thermal Mass Water
The water volume per degree ratio uses Heat storage target and Heat stored per gallon in the order shown.
For the prefilled measurements—heat storage target at 25,000 BTU and heat stored per gallon at 8.34 BTU/F-gal—the calculated answer is 2,997.60 gal/F.
Greenhouse Thermal Mass Water beyond the formula
Useful temperature swing and heat-transfer rate must be considered. Keep estimated covered temperature in a separate Row Cover Temperature Gain Calculator case.
A zero Heat stored per gallon leaves water volume per degree undefined in Greenhouse Thermal Mass Water.
Reading water volume per degree
Greenhouse Thermal Mass Water summarizes its formula as Water volume per degree. Compare this result with Crop Maturity Day Calculator when estimated maturity day is also needed.
Purpose of the water volume per degree estimate
Estimate water volume needed for a heat-storage target per degree. Greenhouse Thermal Mass Water limits that task to Heat storage target and Heat stored per gallon. Cold Frame Temperature Margin Calculator addresses how to compare a cold-frame minimum with the crop threshold.
Save Water volume per degree with the Greenhouse Thermal Mass Water units and scenario name.
Before entering heat storage target
The Greenhouse Thermal Mass Water input panel defines Heat storage target and Heat stored per gallon. Note any Greenhouse Thermal Mass Water conversion.
- Heat storage target
- The Greenhouse Thermal Mass Water target is 25,000 BTU in the starting case.
- Heat stored per gallon
- Its Greenhouse Thermal Mass Water demonstration rate is 8.34 BTU/F-gal.
Collecting data for Greenhouse Thermal Mass Water
Historical dates describe likelihood rather than certainty. Check a current forecast before converting the result into a planting or harvest action. Continue with Frost Protection Water Calculator to calculate water flow required for a frost-protection rate.
Before relying on water volume per degree
How does “Useful temperature swing and heat-transfer rate must be considered.” affect water volume per degree?
No automatic adjustment is applied for it. Use a site-specific value for heat storage target when the condition is present.
