A constant-volume tank initially contains 1 kmol of carbon monoxide CO and 3 kmol of oxygen O2 (no nitrogen) at 25°C and 2 atm. Now the mixture is ignited and the CO burns completely to carbon dioxide CO2. If the final temperature in the tank is 500 K, determine the final pressure in the tank and the amount of heat transfer. Is it realistic to assume that there will be no CO in the tank when chemical equilibrium is reached?
At one point in a pipeline, the water's speed is 3.00 m/s and the gauge pressure is 4.00×10^4 Pa. Find the gauge pressure at a second point in the line 11.0 m lower than the first if the pipe diameter at the second point is twice that at the first..
A footing 3m X 3m carries a pressure of 500 kN/ m2 at a depth of 1m in a sand substrate. The saturated unit weight of the sand is 20 kN/ m3 and the unit weight above the water table is 18 kN/ m3.
An 180 m long 100 mm diameter compressed air pipeline is to be run from a stationary compressor to an air-track drill which requires a flow of 780 l/sec. The pipeline contains 2 large radius bends (R=2d) ,and 4 half closed gate valves.
What is the pressure drop for water at 60 degrees F flowing through 12in schedule 40 pipe at a rate of 500gal/min over a distance of 100 feet.
Oil of a specific gravity of 0.75 is flowing through a 6-in pipe under a pressure of 15 psi. If the total energy relative to the datumplate is 8.0 ft below the center of the pipe is 58.6 ft, determine the flow rate of the oil.
A small city is evaluating disinfection requirements for their drinking water plant. With an average flow of 5 MGD and a peak flow of 9 MGD, determine the controlling CT factor (virus or giardia
Two forces are applied as shown to hook support. Knowing that the magnitude of P is 35 N, determine by trigonometry (a) the required angle a if the resultant R of the two forces applied to the support is to be horizontal, (b) the corresponding magnit..
the linkage shown below is made up of two 3-kg rectangular members 0.4 m by 0.1 m and is flying through the air. at the
The beam is supported by a pin at C and by a short link AB. Each pin has a diameter of 20 mm. Assume L = 1.2 m and θ = 20o. If the average shear stress in the pins at A, B, and C cannot exceed 115 MPa, determine the maximum distributed load wmax th..
if a manometer incline at 45 degrees containing a fluid with specific gravity of a 2.0 using it to measure the pressure in a system, and the fluid levels rise 30 inches. What is the pressure in the system in Lbf/In^2 and H2O
Laboratory clean rooms are often kept at a slightly higher pressure than ambient pressure in order to flush out particulates and keep dust from getting in. If the pressure in such a room is equivalent to 1 mm water greater than the surrounding rooms
A hydraulic jump occurs in a rectangular channel 4.0 m wide. The water depth before the jump is 0.4 m and after the jump is 1.7 m. Compute the flow rate in the channel, the critical depth and the headloss in the jump.
