A horizontal curve on a two lane highway (one lane per direction) has its PC at station 123+70 and its PI at station 130+90. The curve has a superelevation of .06 ft/ft and is designed for 70 mph. What is the station of the PT? Assume a standard lane width of 12ft

The temperature of air decreases as it is compressed by an adiabatic compressor. 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?

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.
