Question

Area of base of a cylinder is 400cm. Water is poured upto depth 0,8m.
Calculate the pressure and thrust of water at the base in SI unit.
(Density of water is 1g/cm)
​

Answer 1

Answer:

Given Area of base of vessel , a = 300 cm2 = 300 × 10-4 m2

Density of water , ρ = 1000 kg m-3

Depth , h = 6 cm = 0.06 m

Acceleration due to gravity , g = 10 ms-2

(a) Pressure = hρg = 0.06 × 1000 × 10 = 600 pascal

(b) Thrust , T = pressure × area = 600 × 300 × 10-4 = 18 N

hope it helps you.
