The 30 degree vertical bend in a pipe with a 2 ft diameter

carries water (rho = 62.4 lbm/ft^3) at a rate of 31.4 cfs. if the

pressure p1 is 10 psi at the lower end of the bend, where the

elevation is 100 ft, and p2 is 8.5 psi at the upper end, where the

elevation is 103 ft, what will be the vertical component of force

that must be exerted by the "anchor" on the bend to hold it in

position? the bend itself weighs 300 lb, and the length l is 4

ft.

An electrical motor raises a 50kg load at a construct velencity .calculate the power of the motor, if it takes 40sec to raise the load through a height of 24m(take g =9.8n/g)

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.

Consider a large isothermal enclosure that is maintained at a uniform temperature of 2000 k. calculate the emissive power of the radiation that emerges from a small aperture on the enclosure surface. what is the wavelength ? , below which 10% of the emission is concentrated? what is the wavelength ? 2 above which 10% of the emission is concentrated? determine the wavelength at which maximum spectral emissive power occurs. what is the irradiation incident on a small object placed inside the enclosure?
