Answer:
The results of a percolation test will determine if there is suitable drainage and the size of the drain field that will be required for a septic system.
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:
The required bulk modulus is
Psi. So, the answer is non of these.
Explanation:
Change in pressure of the fluid is directly proportional to the volumetric strain. The constant of proportionality is the bulk modulus of the fluid.
Step1
Given:
Percentage change in volume is 1%.
Change in pressure is 10000 Psi.
Calculation:
Step2
Volumetric strain is calculated as follows:


Step3
Bulk modulus is calculated as follows:
\frac{\bigtriangleup V}{V}=0.01


K = 1000000 Psi.
Thus, the required bulk modulus is
Psi.
