Question

Через кран в бассейн вливается в минуту 30 ведер воды , а через трубу для стока выливается 840 ведер в час .Если работают одновременно кран и сток , то бассейн наполнится за 12 часов .Сколько ведер воды вмещает бассейн?

Answer 1

12*840 + 12*30*60 = 31680

Answer 2

Calculation of the Water Capacity of the Pool

To determine the water capacity of the pool, we can use the information provided about the flow rate of water through the faucet and the drain pipe, as well as the time it takes to fill the pool when both are in operation.

Let's break down the given information:

- Water flow rate through the faucet: 30 buckets per minute - Water flow rate through the drain pipe: 840 buckets per hour - Time taken to fill the pool when both are in operation: 12 hours

To calculate the water capacity of the pool, we need to find the total amount of water that flows into the pool and the total amount of water that flows out of the pool during the 12 hours.

Calculation of Water Inflow

The water flow rate through the faucet is given as 30 buckets per minute. To find the total amount of water that flows into the pool during the 12 hours, we can multiply the flow rate by the number of minutes in 12 hours:

30 buckets/minute * 60 minutes/hour * 12 hours = 21,600 buckets

Therefore, the total amount of water that flows into the pool during the 12 hours is 21,600 buckets.

Calculation of Water Outflow

The water flow rate through the drain pipe is given as 840 buckets per hour. To find the total amount of water that flows out of the pool during the 12 hours, we can multiply the flow rate by the number of hours:

840 buckets/hour * 12 hours = 10,080 buckets

Therefore, the total amount of water that flows out of the pool during the 12 hours is 10,080 buckets.

Calculation of Water Capacity

To find the water capacity of the pool, we need to subtract the total amount of water that flows out of the pool from the total amount of water that flows into the pool:

Water capacity = Water inflow - Water outflow Water capacity = 21,600 buckets - 10,080 buckets = 11,520 buckets

Therefore, the water capacity of the pool is 11,520 buckets.

Please note that the term "bucket" is used in the given information, and the actual volume of a bucket may vary.
