Ahorizontal pipe has an abrupt expansion from d1 = 8 cm to d2 = 16 cm. the water velocity in the smaller section is 10 m/s and the flow is turbulent. the pressure in the smaller section is p1 = 420 kpa. taking the kinetic energy correction factor to be 1.06 at both the inlet and the outlet, determine the downstream pressure p2, and estimate the error that would have occurred if bernoulli’s equation had been used. take the density of water to be rho = 1000 kg/m3. (round the final answers to one decimal place.)

If the thermal strain developed in polyimide film during deposition is given as 0.0044. assume room temperature is kept at 17.3 c, and thermal coefficient of expansion for the film and the substrate are 54 x 10^-6c^-1 and 3.3 x 10^-6c^-1respectively. calculate the deposition temperature.

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.
