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
Transistors, satellites into space (and animals!), hydropneumatic suspension.
It is possible to replace by lowering tank and warming pipe in hot water.
Yes, the pressure in the pipe is dependant of the height of the column of water above the point you are considering.
normally back to header tank but in some systems where there is no tank there will be a small pipe going through wall to the outside of the property
There is a 4" hole for the inlet near the top of every properly made septic tank. You connect the drain to this by gluing if it's a plastic pipe or by a 'Robar' joint if it's a cast iron pipe.
10 2/7 hours
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.
The fuel tank filler neck is the metal pipe attached to the rear fender that you insert the gas nozzle into to fill your tank.
Pump, pipe, petrol tank.
To drain the over flow from a tank or fixture
The inlet pipe fills 1/5 of the tank per hour.The outlet pipe empties 1/8 of the tank per hour.While inletting and outletting simultaneously, (1/5 - 1/8) = (8/40 - 5/40) = 3/40 of the tank fills per hour.Under those conditions, the tank fills in 40/3 = [ 13 and 1/3rd ] hours.Given an empty tank and activating both pipes at 6 PM, the tank is full at 7:20 AM the next morning.
