Test: Pressure Distribution in a Liquid - Question 1
Save

A rectangular tank is moving horizontally in the direction of its length with a constant acceleration of 3.6 m/s2. If tank is open at the top then calculate the angle of water surface to the horizontal.

Detailed Solution for Test: Pressure Distribution in a Liquid - Question 1

Explanation: tanθ=a/g
tanθ=3.6/9.8
θ=20.15⁰.

Test: Pressure Distribution in a Liquid - Question 2
Save

A rectangular tank is moving horizontally in the direction of its length with a constant acceleration of 4.8 m/s2. The length of tank is 7 m and depth is 1.5 m. If tank is open at the top then calculate the maximum pressure intensity at the bottom. 

Detailed Solution for Test: Pressure Distribution in a Liquid - Question 2

Explanation: tanθ=a/g
tanθ=4.8/9.8
θ=26.07⁰
h= d+(L/2)tanθ
= 1.5+3.5tan26.07
= 3.21 m

Test: Pressure Distribution in a Liquid - Question 3
Save

A rectangular tank is moving horizontally in the direction of its length with a constant acceleration of 5.5 m/s2. The length of tank is 5.5 m and depth is 2 m. If tank is open at the top then calculate the minimum pressure intensity at the bottom. 

Detailed Solution for Test: Pressure Distribution in a Liquid - Question 3

Explanation: tanθ=a/g
tanθ=5.5/9.8
θ=29.28⁰
h= d-(L/2)tanθ
= 2-2.75 tan29.28
= 3.21 m

p=ρ*g*h
=1.9 N/cm2.

Test: Pressure Distribution in a Liquid - Question 4
Save

A rectangular tank is moving horizontally in the direction of its length with a constant acceleration of 4.5 m/s2.The length, width and depth of tank are 7 m, 3m, 2.5m respectively. If tank is open at the top then calculate the total force due to water acting on higher pressure end of the tank. 
Detailed Solution for Test: Pressure Distribution in a Liquid - Question 4

Explanation: tanθ=a/g
tanθ=4.5/9.8
θ=24.64⁰
h= d+(L/2)tanθ
= 2.5+3.5tan24.64
= 4.1 m

F=wAĥ
=9810*2.68*4.1
= 1.07 MN.

Test: Pressure Distribution in a Liquid - Question 5
Save

Detailed Solution for Test: Pressure Distribution in a Liquid - Question 5

Test: Pressure Distribution in a Liquid - Question 6
Save

A tank containing water upto a depth of 750 mm is moving vertically downward with a constant acceleration of 3.45 m/s2. Find the force exerted by fluid of specific gravity .85 on the side of tank,width of tank is 2m 
Detailed Solution for Test: Pressure Distribution in a Liquid - Question 6

Explanation: p=ρ*g*h*(1-a/g)
=750*9.81*0.75*(1-3.45/9.81)
=3577 N/m2
F=wAĥ
= 0.5*0.75*3984.5*2
= 2682.75 N.

Test: Pressure Distribution in a Liquid - Question 7
Save

A tank containing water upto a depth of 650 mm is stationary. Find the force exerted by fluid of specific gravity .55 on the side of tank,width of tank is 1.5m 
Detailed Solution for Test: Pressure Distribution in a Liquid - Question 7

Explanation: p=ρ*g*h
=550*9.81*0.65
=3507 N/m2
F=wAĥ
= 0.5*0.65*3507*1.5
= 1709.7N.

Test: Pressure Distribution in a Liquid - Question 8
Save

The pressure intensity at the bottom remains same, even if the tank moves with constant horizontal acceleration.
Detailed Solution for Test: Pressure Distribution in a Liquid - Question 8

Explanation: The pressure intensity at the bottom differs due to variation in height as tank moves with constant acceleration.

Test: Pressure Distribution in a Liquid - Question 9
Save
