If the pipe is made from a material having a modulus of elasticity E and Poisson's ratio ν, determine the change in volume of the material.

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

Find the kinematic pressure of 160kpa. for air, r-287 j/ kg k. and hair al viscosity of air at a temperature of 50°c and an absolute (10 points) (b) find the dynamic viscosity of air at 110 °c. sutherland constant for air is 111k

Modern high speed trains do not have perpendicular expansion gaps where rails are joined end-to-end any more they are mostly welded together but what might happen if there was a spell of particularly hot weather that causes inspection of the tracks?
