Determine the absolute pressure and density at vail pass

Reference no: EM13258202

The maximum power output capability of an engine decreases with altitude because the air density and hence the mass flow rate of air decreases. A truck leaves Denver (elevation = 1620m) on a day when the local temperature and absolute pressure are 15 degrees Celsius and 94kPa, respectively. It travels through Vail Pass (elevation 3260m), where the temperature is also 15 degrees Celsius. Assuming that the temperature is constant with altitude, determine the absolute pressure and density at Vail Pass. Assuming that the maximum power output is proportional to density, how much less maximum power (in percent) does the truck have compared to Denver?
