Agas contained within a piston cylinder assembly undergoes two processes a and b between states 1 and 2. p1=10 bar, v1= 0.1m^3, u1=400kj, p2=1 bar, v2=1.0 m^3, u2= 200kj. pv= constant in process a. constant volume process followed by a constant pressure process in process b. for each process, sketch the pv diagram and evaluate w12 and q12 associated with each process in kj.

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?

Carbon dioxide gas expands isotherm a turbine from 1 mpa, 500 k at 200 kpa. assuming the ideal gas model and neglecting the kinetic and potential energies, determine the change in entropy, heat transfer and work for each kilogram of co2.

Which of the following controllers anticipates the future from the slope of errors over time? a)-proportional b)-on/off c)-integral d)-derivative.
