Question:
A tank is filled at the rate of 324 cubic inches per second. It is emptied at the rate of 15 cubic yards per hour, what will be the change after 4 hours?
Answer:
40y³
Step-by-step explanation:
First the starting point in relation to how much liquid is in the tank is not known. It is assumed to be empty. Next the size of the tank is not known. It is assumed it is capable of holding the amount of liquid that will accrue after the 4 hours. It is also assumed both filling and emptying happen at the same time and that the pipe emptying the tank is in the very bottom of the tank.
Now the maths…
1y³ is 46,656inch³. Fill rate per hour is …
(324×60²)/46,656 = 25y³/hr
The effective fill rate is 25 - 15 = 10y³/hr
In four hours the tank would contain 40y³ of liquid.
