That really depends on what fluid is being forced through the pipe. If it's 5,000 gallons of single malt scotch per hour, the pressure is relatively low. If it's 5,000 gallons of molasses per hour, the pressure is relatively more higher.
On average a general 5000# to 7000# fork lift will use 1.5 gallons of Propane.
To find the number of gallons that would go through the valve in 91 hours, multiply the flow rate by the time: (281 \text{ gallons/hour} \times 91 \text{ hours} = 25,651 \text{ gallons}). Therefore, 25,651 gallons would go through the valve in 91 hours.
The gallons per hour that come out of a hose depends upon two things: the diameter of the hose, and the water pressure. Since both of these vary, there is no single answer to that question. However, a one inch diameter garden hose at an average household water pressure could be expected to yield about 200 gallons per hour, in my estimation. Your mileage may vary.
200 hours
25,571 gallons
1 cubic foot equals 7.48 gallons so 106 cubic feet per hour would equal 793 gallons per hour or 13 gallons per minute
The standard specific fuel consumption for a heat engine is 0.5 lb per HP per hour. A 3 MW generator is 4000 HP but allowing for conversion efficiency the engine would probably have to provide 5000 HP, so using the above specific fuel consumption the rate of fuel use would be 2500 lb fuel per hour. With a specific density of 0.8 2500 lb of fuel would have a volume of 310 gallons. This generator uses 310 gallons per hour, therefore 100,000 gallons would last 100,000/310 hours or 322 hours, just under 2 weeks.
Depending on the type of need for the pressure washer will depend upon the amount of money that will need to be spent. A job requiring less power would require a relatively inexpensive pressure washer. The average prices generally range in the two to three hundred dollar range.
About 171.6 gallons per hour.
18.75 gallons per hour.
Cubic feet per hour x 7.48 = gallons per hour
The first step is to convert fluid ounces into gallons then multiply that by 60 to get gallons per hour:4 x 0.0078 (gallons per fl. oz.) = 0.0312 gallons per minuteNext:0.0312 x 60 = 1.9 gallons per hour
