4-35 a well-insulated rigid tank contains 5 kg of a saturated liquid-vapor mixture of water at 100 kpa. initially three-quarters of the mass is in the liquid phase. an electric resistor placed in the tank connected to a 100-v source, and a current of 8 a flows through the resistor when the switched is turn on. determine how long it will take to vaporize all the liquid in the tank. also, show the process on a t-v diagram with respect to saturation lines.

If the thermal strain developed in polyimide film during deposition is given as 0.0044. assume room temperature is kept at 17.3 c, and thermal coefficient of expansion for the film and the substrate are 54 x 10^-6c^-1 and 3.3 x 10^-6c^-1respectively. calculate the deposition temperature.

An electrical motor raises a 50kg load at a construct velencity .calculate the power of the motor, if it takes 40sec to raise the load through a height of 24m(take g =9.8n/g)

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?
