water is pumped from a lower reservoir to a higher reservoir by a pump that provides 20 kw of useful mechanical power to that water. the free surface of upper reservoir is 45 m higher than the surface of the lower reservoir. if the flow rate of water is measured to be 0.03 m3/s, determine the irreversible head loss of the system.

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?
