Write a c program that inputs an integer that represents a length of time in seconds. the program should then output the number of hours, minutes, and seconds that corresponds to that number of seconds. for example, if the user inputs 50391 total seconds then the program should output 13 hours, 59 minutes, and 51 seconds.

The y form of iron is known as: a) ferrite b) cementite c) perlite d) austenite

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.

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?
