1. A composite with uni-directional fiber reinforcement is made using two unknown constituent materials, Material A which is the fiber and Material B which is the matrix. The elastic modulus of Material A is 150 GPa and the elastic modulus of Material B is 10 GPa. If Material A is 40 % of the overall composite by volume, determine

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

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.
