It is desired to produce a continuous and oriented carbon fiber-reinforced epoxy having a modulus of elasticity of at least 60 gpa (8.7 × 106 psi) in the direction of fiber alignment. the maximum permissible specific gravity is 1.40. given the following data, is such a composite possible? assume that composite specific gravity may be determined using a relationship similar to the equation for the modulus of elasticity of a continuous and aligned fibrous composite in the longitudinal direction.

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.

Fluids at rest possess no flow energy. a)- true b)- false

Water at 55c flows across a flat plate whose surface temperature is held constant at 95c. if the temperature gradient at the plate's surface for a given value of x is 18 c/mm, find a) local heat transfer coefficient. b) heat flux
