Answer:
Relative roughness = 0.04
Explanation:
Given that:
Diameter = 5 cm
roughness = 2 mm
At inlet:
Minor coefficient loss
At exit:
Minor coefficient loss
Height h = 4m
Length = 5 m
To find the relative roughness:
Relative roughness is a term that is used to describe the set of irregularities that exist inside commercial pipes that transport fluids. The relative roughness can be evaluated by knowing the diameter of the pipe made with the absolute roughness in question. If we denote the absolute roughness as e and the diameter as D, the relative roughness is expressed as:
Answer:No
Explanation:
Given
Block A is at height h and released from rest
Initial Energy possessed by block A is equal to Potential energy of Block which is given by
where m=mass of block
After releasing the block, block first reaches to the bottom of the circle and then uses this energy to reach a top point of the loop.
But as soon as block reaches the top point of the loop it acquires the energy which is equal to Initial energy i.e. all the energy is stored in the form of potential energy and there is no kinetic energy so the block will not able to move further and fall from the top point.
