if a tank is emptied in 5 minutes fire pump there is pumping @ 300 gallons per minute how long will it take to empty the tank with pump that with pump @ 500 gallons per minute
Answers
Answer:
Multiply the flow rate, measured in cubic meters per hour, by 4.4 to convert it to gallons per minute. For example, if 100 m^3 of fluid go through the exchanger each hour: 100 × 4.4 = 440.
Multiply this flow rate by the refrigerant's temperature rise. For example, if fluid enters the exchanger at 59 degrees Fahrenheit and rises to 72 degrees Fahrenheit: 440 × (72 - 59) = 5,720.
Multiply this result by 500, a conversion factor that takes the fluid's heat absorption rate into account: 5,720 × 500 = 2,860,000. This is the unit's energy transfer rate, measured in BTUs per hour.
Multiply this rate by the number of hours for which the appliance runs. For example, if you are calculating the heat transferred over the course of half an hour: 2,860,000 × 0.5 = 1,430,000. This is the number of BTUs that the heat exchanger moves.
Answer:
27 is the right answer
Step-by-step explanation:
Given m varies inversely as t, and m = 9 when t = 6, find the variation constant and the inverse variation equation. Then determine m when t = 27.
