A well-insulated rigid vessel of volume 0.2 m^3 is divided into two equal compartments by thin diaphragm, as illustrated in the accompanying figure. One of the compartments is a vacuum. The other is a fluid at a pressure of 200 kPa and a temperature of 125 degrees Celsius. The diaphragm is ruptured and fluid fills the entire volume of the vessel. Assume that the fluid is an ideal gas. After you have determined Qsub12, Wsub12, and delta U for the process, calculate the final temperature of the gas.
water is pumped into an irrigation pond at 250 gal/min for 24 hours. the pond area is 2500 square feet. Determine the depth of water in the pond .Provide answer in ft and m
To avoid the salinization of soil in a farming area, parallel drainage canals are to be installed to maintain the water table at a depth of at least 4m below the ground surface. It is thought that no evapo-transpiration would occur below that dept..
Water is transferred at a rate of 2.1cfs from an upper reservoir to a lower reservoir by a concrete pipe 3000ft long. The difference in water level is 60ft. Determine the size of pipe for a water temperature of 60 degrees Fahrenheit. Apply The Darcy-..
The 35-in pump of fig. 11.7b is used to pump 24000 GPM of water (68ft) at 710 rpm from a large tank whose surface is at atmospheric presure. the head loss from tank to the pump inlet is 3ft.
A concrete mix with a 3 inch slump, w/c ratio of 0.50, and sand with a fineness modulus of 2.4 contains 1.700 lb/yd^3 of coarse aggregate. Compute the required weight of coarse aggregate per cubic yard.
If metal sorption to algae can be modeled by a Langmuir isotherm, determine the mass distribution (sorbed vs dissolved) of lead in the marsh. Langmuir Isotherm Parameters Cs , sat 100 mg/g a 0.1 L/mg
A 1600 ft long sag verical curve (equal tangent) has a pvc at station 1200+00 and elevation o 1500 ft. the initial grade is -3.5% and the final grade is 6.5%. determine the elevation and stationing of the low point, pvi and pvt.
Finally, the wreckage is removed, and the freeway is restored to full capacity (4000 veh/h) at 8:31 a,. Assume D/D/1 queuing to determine time of queue dissipation, longest queue length, total delay, average delay per vehicle, and longest wait of ..
A PVC pipe with a diameter of 30 inches will carry a flow of 20 cfs. the bottom slope is 0.005 and the roughness coefficient is 0.015. determine the normal depth, critical depth, velocity and the froude number.
determine the power that must be supplied to the motor at this instant. The motor has an efficiency of 76 %. Neglect the mass of the pulleys and cables.
Roe is the ratio of nonprestressed reinforcement in a section, and roe balanced is the ratio of tensile reinforcing producing balanced strain condition. Show cross sections, including bar sizes, arrangements, and spacing.
