Pipe 1: 0,5 tanks per hour (2 hours to fill)
Pipe 2: 0,2 tanks per hour (5 hours to fill)
If we let X be the time in hours to fill the tank:
0,5 * X + 0,2 * X = 1 (one tank filling)
0,7 * X = 1
X = 1 ÷ 0,7 = 1.428571429... ≈ 1.43 hours or almost 1 hour 26 minutes

If if takes pump A 6 hours to fill a tank and it takes pump B 12 hours to drain it then how long will it take to fill the tank?
Pump 'A' can fill 1/6 of the tank in one hour. 1/6 is the same as 2/12 Pump 'B' can drain 1/12 of the tank in one hour. If both pumps are running at the same time, then in one hour 2/12 get filled and 1/12 gets drained, and the net effect is 1/12 getting filled in that hour. If the tank is initially empty and both pumps start at the same time, then the tank will fill in 12 hours. *edit* It takes six hours if pump B is left off.

7 pipes canfill a water tank in 6 hours Find the time required for 9 pipes to fill up the tank?
If 7 pipes can fill a water tank in 6 hours, then 1 pipe would take 7 times 6 or 42 hours. Take 42 and divide by 9, and you get 4 2/3 hours. That is the time it would take for 9 pipes to fill the tank.
One sprinkler can fill the fountain in 3 hours Another can fill it in 6 hours How long will it take to fill the fountain with both sprinklers operating?
wellto answer it we'll have to kno how much the fountain can hold . plz restate your question :)
A tank can either be filled in 12 hours by Pipe A or in 8 hours by Pipe B How long will it take both pipes woorking together to fill the tank?
Pipe A fills 1/12 of the tank per hour, and Pipe B fills 1/8 of the tank per hour. Together, they fill 1/12+1/8 of the tank per hour. 1/12+1/8=(1*8)/(12*8)+(1*12)/(12*8)=(8+12)/(12*8)=20/96=5/24 of the tank per hour So, it would take 1/(5/24)=24/5 = 4.8 hours to fill the tank with both pipes.
A pool can be filled by one pipe in 7 hours and by a second pipe in 2 hours How long will it take using both pipes to fill the pool?
In one hour first pipe fills 1/7th of pool, other pipe fills one-half, so together in one hour they fill 1/7 + 1/2 ie 9/14 so would take 14/9 hours (93 and a third minutes) to fill the pool. ie 1 hr 33 min 20 sec
At the swimming pool certain pipe can fill it in 5 hours another pipe can fill it in 2 hours a third pipe can empty it in 6 hours with all 3 pipes turned on how much time would it take to fill?
The reciprocal of the added reciprocals. 1/T = 1/A + 1/B + ... 1/Z In your case: 1/T = 1/5 + 1/2 +1/6 1/T = 6/30 + 15/30 + 5/30 1/T = 26/30 T = 30/26 = 15/13 hours = 1 hour 9 minutes 14 seconds
Pipe A can fill tank in 30 mins and pipe B in 28 mins If 34th tank is filled by pipe B alone and both are opened how much time is required by both pipes to the tank completely?
pipe a fill 1/4th part in 7 mins and pipe b in 7.5 mins hence both tank will fill 1/4th of tank in 7+7.5/4 = 3.6 mins
My toilet tank won't fill back up. Are the pipes frozen or is there a corroded valve. How can I find out and what should I do?
replace the fill valve
If you have a 6000 liter tank it takes one pipe to fill it in 50 minutes and the other pipe in 75 minutes how long will it take both pipes at the same time?
It would take the too pipes 30 minutes to fill the tank when working together.This figure can be found in the following manner:Find the fill-speed of the first pipe50 minutes to fill 6000 Liters. 6000L/50m gives us 120L/m (liters-per-minute)6000 Liters in 75 minutes = 6000L/75m = 80L/mNext find the speed of the second pipeNow we combine the two rates (120+80), and we find that the pipes have a combined fill-speed of 200L/mFinally, we determine that it takes 30 minutes to fill the tank at 200L/m
An empty swimming pool can be filled to capacity through an innlet pipe in 3 hours and it can be completely drained by a drained pipe in 6 hours if both pipe are fully open at the same time in how man?
Assuming the flow rate is constant (in a real system, this probably will not be the case, at least for the drain; it probably drains faster when nearly full than when nearly empty), then for convenience sake let's say the pool holds six units of water. It fills at 2 units per hour and drains at 1 unit per hour. If both pipes are open, the net gain is 1 unit per hour, so it will fill in six hours (and then start overflowing unless both pipes are shut off).
A pipe that fills 25 of a tank in 1 hour will fill in completely in hours?
If that's 25%, it will fill in four hours. If that's 2/5 (40%), it will fill in 2.5 hours.
