Answer:
Explanation:
Given

Volume Flow rate 
Length 
radius 

According to Hagen-Poiseuille Equation
difference in Pressure is given






Force = Work/distance
Force = 150/10
= 15 Newtons
Force = 15 Newtons
Therefore, 15 newtons of force is applied to the body when 150 joules of work
is done in displacing the body through a distance of 10m in the direction of the force.
