Answer:

So the bouy does not float with its axis vertical
Explanation:
From the question we are told that:
Diameter 
Length 
Weight 
Specific weight of sea water 
Generally the equation for weight of cylinder is mathematically given by
Weight of cylinder = buoyancy Force

Where

Therefore

Therefore
Center of Bouyance B

Center of Gravity

Generally the equation for\BM is mathematically given by

Therefore

Therefore

Therefore

So the bouy does not float with its axis vertical
Answer:
v = 1.076 m /s
Explanation:
Initial volume of balloon = 4/3 x 3.14 x (9.905/2)³
=508.56 m³
Final volume of balloon = 4/3 x 3.14 x (16.502/2)³
= 2351.73 m³
Increase in volume = 1843.17 m³
Cross sectional area of inlet A = 3.14 x( 1.458/2)²
A = 1.6687 m²
Volume rate of flow of air = cross sectional area x velocity of inflow
= 1 .6687 V [ V is velocity of inflow ]
Total time taken = Increase in volume / rate of flow of air
17.108 X 60 = 1843.17 / 1.6687 V
V = 
v = 1.076 m /s
Answer:

Explanation:
Given that
At top

We know that







So
m/s
We know that flow rate Q=AV

By putting the values


To find the flow rate we do not need the direction of flow,because we are just doing balancing of energy at inlet and at the exits of pipe.
