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.

An inlet pipe can fill a large water tank in 5 hours An outlet pipe can empty the same water tank in 8 hours Given an empty water tank at 6PM activate both pipes Question What time on?

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.

Why is copper used for water pipes?

Copper is used as hot water pipes because the copper will not corrode when the hot water goes through the pipes


At what temperature do pipes crack?

Water pipes should not of themselves crack at any temperature, however if pipes have water in them the water will freeze at temperatures below 0oC. If this happens then as the water freezes it will expand (ice is less dense than water) and as it expands it will either stretch metal pipes until they burst or crack ceramic pipes. For this reason external water pipes are buried at a depth to which the frost will not penetrate and internal water pipes are lagged to keep them warm.

A plumber has put 18 gallons of antifreeze into my water pipes can the antifreeze interact with copper or lead pipes or pipes with lead soddering and cause contamination to the water?

I can't think you are talking drinking water pipes because anitfreeze is poisonous. Nor should you have lead pipes or lead solder in drinking water pipes. So either sleeve pipes or heating pipes then. Antifreeze has inhibitors designed to prevent corrosion.
