Question

Q7) At the depth of 1000 M
pressure due to liquid is
times.
10Pa
100Pa
1000pa
10,000Pa​

Answer 1

Answer:

Each 10 metres (33 feet) of depth puts another atmosphere (1 bar, 14.7 psi, 101 kPa) of pressure on the hull, so at 300 metres (1,000 feet), the hull is withstanding thirty atmospheres (30 bar, 441 psi, 3,000 kPa) of water pressure

Given: h=1000m,d=1.03×10

3

kg/m

3

,g=10m/s

2

The absolute pressure is given by: absolute pressure = pressure of water + atmospheric pressure

P=hdg+1atm=1000×1.03×10

3

×10+1atm=1.03×10

7

Pa+1atm

P=103atm+1atm=104atm
