Two water reservoirs a and b are connected together through a 430m long pipe of 300 mm diameter and an inner surface roughness of e = 0.3 mm. a valve with a loss coefficient of k 0.75 (partially open) is fitted in the pipeline for flow control. if the water level in reservoir a is 30 m above b and ignoring other minor losses, calculate the water flow rate in the pipe using the iteration method and the moody chart.

What precautions should you take to prevent injuries when dealing with heavy loads?

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false

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?
