Homework Assignment 3 ME 3392: Fluid Mechanics Q1. A needle has a length of 3.2 cm. When placed gently on the surface of water ($\sigma$ = 0.073 N/m) in a glass, this needle will float if it is not too heavy. What is the weight of the heaviest needle that can be used in this demonstration? Q2. When water at 60 $^\circ$C flows through a converging section of pipe, the pressure decreases in the section. Estimate the minimum absolute pressure that can develop without causing cavitation. Express your answer in SI units. Q3. A layer of water flows down an inclined fixed surface with the velocity profile shown in Figure. Determine the magnitude and direction of the shearing stress that the water exerts on the fixed surface for U = 2 m/s and h = 0.1 m. Take the absolute viscosity of 1.002 x 10$^{-3}$ N-s/m$^2$.
Use appropriate algebra techniques and the Laplace transform table to find the inverse Laplace transform of F(s). \(F(s) = \frac{6s^2 - 13s + 2}{s(s-1)(s-6)}\)
Problem 1: We want to design a light-weight and stiff bar under uniaxial load F. The total length of the bar is fixed but the cross-section area can be varied. Pick up the most efficient materials (A to F) from the following Ashby diagram. (Hint: plot lines corresponding to the material index).
