Question

Water flows out through a circular pipe whose internal diameter is 2cm and the rate of time is 6m/s into a cylindrical tank. the radius of base is 60cm. find the rise in the level of water in 30 second. ✔️✔️CORRECT ANSWER WILL MARK AS BRAINLIST ✔️✔️​

Answer 1

SOLUTION :-

• Radius of cylindrical tank = 60cm ( change in metre) = 60/100 = 6/10m
• height = ?
• diameter of pipe = 2cm = 2/100m
• Radius = diameter/2 = 2/100×2 = 1/100m

• in 1sec water flows = 6m
• in 60sec water flows = 6×60
• in 1 min water flows = 6×60
• in 30min water flow = 6×60×30

(→ height = 6×60×30m

Now,

• According to question

→ πr²h = π*1/100 * 1/100 * 60 * 6 * 30

→ 6/10*60/100*h = 1*6*60 * 30/100*100

→ h = 30/10

→ h = 3m

★ Hence,

• →) the level rise in 30 min = 3m$\sf$
