Solve the each part of given question:
Question: A plastic straw 20.0 cm long and 3.00 mm in diameter is filled with honey. Suppose that when you blow on one end of the straw, the pressure difference between the two ends of the straw is 0.05 atm. Assume that somehow, the honey is constantly replenished so that the straw is always filled with honey. Take the density and viscosity of honey to be 1.42 g/cm3 and 10,000 cP.
Part A: Starting from a free-body diagram analysis, find the flow velocity in the straw as a function of the distance from the straw's symmetry axis.
Part B: What mass of honey flows out of the straw in 1.0 s?
Part C: What is the magnitude and direction of the force the honey exerts on the straw?
I need help to solve the above question and hint: Be careful to distinguish between the force the honey exerts on the straw and the force the straw exerts on the honey.
