Question

rectangular reservoir is 120 metre long and 75 metre wide find the speed of water flowing into its square pipe of 20 cm side such that the water rises by 1.2m in 9 hours

Answer 1

Answer:

Hence the volume of water that flows through pipe is 18x × 0.2m × 0.2m. Now the water in reservoir is filled due to the water that has flown through the pipe. Hence the speed of water is 30km per hour.

Step-by-step explanation:

Hence the volume of water that flows through pipe is 18x × 0.2m × 0.2m. Now the water in reservoir is filled due to the water that has flown through the pipe. Hence the speed of water is 30km per hour.
