Webhours, calculate the amount of water applied. From Eq. 5, we know that the system applies 0.096 inches per hour, multiply that by 8 hours: REMEMBER the efficiency: the 0.77 inches is the gross amount of water applied. To calculate the net water applied, multiply the gross water applied by the efficiency (0.95): WebYour turfgrass needs ¼ inch of water per day to stay green. Therefore, your evapotranspiration rate is 0.25 inches per day. This is the amount or depth of water that needs to be replaced by the irrigation system. ...

WebFor example, a 3 inch per hour rainfall will build up to a 3 inch depth on a flat roof in one hour, at the rate of 1.87 gallons per hour/sq. ft. or .0312 gallons per minute/sq. ft. (See Figure 7). Using a 10,000 sq. ft. roof area, the 3 inch rainfall will produce 18,700 gallons in one hour at the rate of 312 gallons per minute.
