The small 5-oz slider A moves without appreciable friction in the hollow tube, which rotates in a horizontal plane with a constant angular speed of ω=7 rad/sec. The slider is launched with an initial speed of dr=60 ft/sec relative to the tube at the inertial coordinates x=6 in. and y=0. Determine the agnitude P of the horizontal force exerted on the slider by the tube just before the slider exits the tube.

An air conditioning system consist of a 5 cm diameter pipe, operating at a pressure of 200 kpa. the air initially enters the pipe at 15°c with a velocity of 20 m/s and relative humidity of 80%. if the heat supply throughout the process is 960 w, determine the relative humidity and the temperature at the outlet

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?
