A workpiece 2-in in diameter is to be machined on a lathe to 1.5-in in diameter. The total length of the workpiece is 3-in. It is recommended from handbook that a feed of 0.06 ipr, a cutting speed of 208 fpm, and a maximum depth of cut of 0.1-in be used. A 0.25-in overtravel should be used for cutter clearance. How long will it take to finish the part in minutes

During a steady flow process, the change of energy with respect to time is zero. 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?

Water at 55c flows across a flat plate whose surface temperature is held constant at 95c. if the temperature gradient at the plate's surface for a given value of x is 18 c/mm, find a) local heat transfer coefficient. b) heat flux
