Steam flows through a device with a stagnation pressure of 120 psia, a stagnation temperature of 700°F, and a velocity of 900 ft/s. Assuming ideal-gas behavior, determine the static pressure and temperature of the steam at this state.
A curved section of a two-lane highway measured in the field was found to be 22 feet wide and have an elevation difference of 1.37 feet between the outside and inside edges of the pavement
The owner of a dive shop wants to purchase a constant displacement air compressor capable of simultaneously filling 10 SCUBA tanks. each having a volume of 0.4 ft^3. in 20 minutes. The initial pressure is 500 psig and the final pressure is 3000 psig...
A 5% upgrade on a six-lane freeway (three lanes in each direction) is 1.25 mi long. On this segment of freeway, the directional peak-hour volume is 3800 vehicles with 2% large trucks and 4% buses (no recreational vehicles), the peak-hour factor is 0...
In 2003 at Holloman Air Force Base in New Mexico, test engineers set a world record by moving 192 lb payload at 6,453 miles per hour in a rocket sled. The rocket sled track, built in 1954, is 15.44 km in length.
The medium contains a wetting phase in equal proportions. Calculate the numerical value of the Leverett J- function for this idealized porous medium. Assume the wall thickness of the capillary tube to be negligible small.
It is required to reduce a pipe of diameter 8 in to a minimum diameter pipe that allows the downstream velocity not to exceed twice the upstream velocity. Determine the diameter of the pipe. Assume smooth transition
A room is heated by a baseboard resistance heater. When the heat losses from the room on a winter day amount to 6500 kJ/h, the air temperature in the room remains constant even though the heater operates continuously.
A permanent endowment at the University of Alabama is to award scholarships to engineering students. The awards are to be made beginning 5 years after the $10 million lump-sum donation is made.
Steam at 500 kPa and 200 C is mixed adiabatically with cold water at the same pressure and 15 C to produce 1 kg/s saturated liquid water at 500 kPa. The rate of entropy generation in the surroundings is? in kw/K
Assuming that the coefficient of friction between the tires and the pavement is 0.30, determine the braking distance downhill and the percent grade of the highway at that section of the road.
At a specified point on a highway, vehicles are known to arrive according to a poisson process. Vehicles are counted in 20 second intervals, and vehicle counts are taken in 120 of these time intervals.
What is the water content and liquidity index of the fines in compacted mass?A civil engineer used a 30-m tape in measuring an inclined distance. The measured length on the slope was recorded to be 459.20 m long.
