Final velocity of a scattered particle A photon of energy i = hν scatters from a free particle at rest of mass m0. The photon is scattered at angle θ with energy f = hν, and the particle flies off at angle φ. Find an expression for the final velocity u of the particle.
Air at 1 atm, 15°C, and 60 percent relative humidity is first heated to 20°C in a heating section and then humidified by introducing water vapor. The air leaves the humidifying section at 25°C and 65 percent relative humidity. Determine
