The daughter acme home with a pool draining formula worksheet from school.
It seems like I should be able to figure this out, but..alas. Water = w t= hours w=-250(t-5) is the formula. GPH pumped out? Gallons in pool at start, and how long to pump out the pool. Thanks, guys. |

Gallons in pool at start, and how long to pump out the pool. Thanks, guys. Gallons of water in pool at start - just substitute t=0 into the equation. The answer is 250*5= 1,250 (presumably gallons) How long? Solve for the t when w=0. stick in w=0 and you'll solve for t (the answer is t=5, which is presumably 5 hours) |
| A man on vacation is walking along the beach and happens upon a scene where a man is laying halfway out of the water white as a ghost and somebody is vigorously giving him chest compressions. The man on vacation shouts "you need to pull him all the way out of the water!" One of the onlookers yells "why, are you a doctor?" "No I'm a hydraulic engineer." |
