Hey mates... ✌❤
water flows in stank 1 0,100 m at the base, through a pipe whose cross section is 2dm by 1.5 dm at the speed of 15 km per hour. In what time will the water be thelree metres deep?
Please don't give useless answers.. plz

Answer:
Volume of water in the tank, when depth is of 3 m,
V = 150 × 100 × 3 = 45000 m^3
Rate of volume of water flowing = 2 × 1.5 × 10^-2 × 15000 m^3/hr = 450 m^3/hr
Thus,
Time taken = 45000/450 hr = 100 hours
Answer:
100 hours
Step-by-step explanation:
Given:
water flows in stank 150 * 100 m at the base, through a pipe whose cross section is 2dm by 1.5 dm at the speed of 15 km per hour.
To Find:
In what time will the water be three metres deep.
Solution:
Lengh = 150 m, Breadth = 100 m, Height = 3 m
Volume of tank = 150 * 100 * 3 = 45000 m^3.
Length = 2 dm = 0.2 m, Breadth = 1.5 dm = 0.15 m, height = 15 km = 15 m
Volume of water flowing through pipe in 1 hour :
==> 0.2 * 0.15 * 15000
==> 450 cm^3
Thus, Time taken by the pipe to fill the tank,
==> 45000/450
==> 100 hours
Result:
Time taken = 100 hours.
