A container with a plunger compresses one pound mole of an ideal gas from 1 atmospheres pressure to 10 atmospheres. Calculate the amount of work done if the process is considered to be polytropic. Assume the temperature to be 273K and the value of k for the process to be 1.4. All losses are neglected.
Using darcy-weisbach equation, calculate the major friction head loss for a 24 inch diameter, 120 ft long pipe that can carry water with a flow rate of 5 cfs. Assume the temperature of water is 70 deg F and the roughness of the pipe is 0.0016 ft.
The beams support one-way slabs, 6 inches thick that span 20 feet center to center. Assume that the beams are 16 inches wide and 24 inches deep. Determine the dead load in pounds per linear foot for the beams, from the concrete structure alone.
A 1 m diameter unfinished concrete pipe (n = 0.015) has a slope of So = 0.001 and conveys water at Q = 0.5 m3/s. Find the normal depth yo and critical depth yc.
What must be the radius of the steel wire if it is to stretch the same distance as the aluminium wire, so that the two wires maintain equal lengths after the masses are attached?
Aerotron Electronics is considering purchasing a water filtration system to assist in circuit board manufacturing. The system costs $40,000. It has an expected life of 7 years at which time its salvage value will be $7,500.
Explain CBR method of pavement design with one example.
A 3000-lb car has a maximum speed (at sea level and on a level, paved surface) of 140 mi/h with 16-inch-radius wheels, a gear reduction of 3.5 to 1, and a drivetrain efficiency of 92%. It is known that at the car's top speed the engine is producin..
A flow has circular streamlines. At t=0 the flow is in the clockwise direction and the angular velocity is pi rad/s. This flow exists for 1 s, and then reverses to counterclockwise with an angular velocity of -pi rad/s for 1 s.
Water flows into and out of a 5 liter tank at a rate of 1 L/min. Within the tank, the mineral apatite is dissolving at a rate of 3x10^-10 moles of Si per m^2 per sec. If the tank contains 10g of the apatite with a specific surface area of 2 m^2/g,
What are the quantitative measures of reliability (discuss measures for hardware, software, personnel, facilities, and data)?
shaped nozzle such that the velocity along the center line of the flow increased from 1.5 m / s to 15 m / s at a distance of 37.5 m. specify the amount of convective acceleration at the beginning and end of the range.
A fan blade, initially at rest, rotates with a constant rotational acceleration of 0.9rad/s^2. What is its rotational velocity at the instant it goes through an rotational displacement of 5 radians
