Two m^3 of xenon(Xe) are contained in a closed rigid tank at 70 degree C and 2 bar. The tank is heated to a pressure of 10 bar. Assuming that Xe behaves like an ideal gas with a specific heat ration of 1.7, calculate the final temperature of Xe in degree C.
When a theoretical cutting plane is passed through an axially loaded prismatic bar, perpendicular to the longitudinal axis of the bar, and one side is analyzed as a free-body diagram, there is a uniformly distributed force acting on the bar's cros..
Neglecting the effect of altitude of local gravitional acceleration, determine the vertical distance climbed. Assume an average air density of 1.18 kg/m^3.
An equal tangent vertical curve conects an initial grade of -3% and a final grade of +1% and is designed for 60mi/h. The PVI is at station 250+50 and elevation 732 ft. What is the station and elevation of the lowest point on the curve
A traffic signal control is being designed for a four-leg intersection on a divided highway with the characteristics shown in the table below. Determine an appropriate length of the yellow interval for each approach and how you will provide it.
Two 9-in.-diameter pipes (pipe 1 and pipe 2) are supported every 7.5 ft by a small frame like that shown. Knowing that the combined weight of each pipe and its content is 30 lb/ft and assuming frictionless surfaces
At a temperature of 9°C, a 2-mm gap exists between two polymer bars and a rigid support. Bars (1) and (2) have coefficients of thermal expansion of t1 = 102 x 10-6 /°C and t2 = 66 x 10-6/°C, respectively.
A substance for which k is a constant undergoes an isothermal, mechanically reversible process from initial state(P1-->V1) to (P2-->V2), where V is a molar volume. a) Starting with the definition of k, show that the path of the process is described
Why is the ‘time value of money' important for the evaluation of engineering projects? Provide at least one practical example to support your view (max 2 pages)
Typical water supply at a faucet in any building is conveyed in copper pipe that is ½" in inside diameter, with a wall thickness of 0.040". If the water pressure is 50 psi and the valve is closed (meaning that water is not flowing)
An industry is illegally dischargingbenzeneinto a river. The concentration in the river atthe point of discharge is 0.2mg/L. A drinking water treatment plant (DWTP) is located 1.5km downstream. The watervelocity in the riveris 0.35km/day.
A vertical curve of 600 ft in length is used to connect two tangents with the following locations: Tangent 1.- Point 1, Sta = 59+00, El = 1250.0' Point 2, Sta = 72+00, El = 1190.0' Tangent 2.- Point 1, Sta = 72+00, El = 1190.0' Point 2, Sta = 84+0..
The break up of a liquid jet into droplets of diameter d depends on the jet diameter D, the jet velocity V, viscosity Mu, density rho,and surface tension sigma.
