For the pulley system shown, each of the cables at A and B is given a velocity of 2 m/s in the direction of the arrow. Determine the upward velocity v of the load m.
Imagine a slide with a radius of 1.5 m and a vertical drop of 2 m per turn. Further suppose that one of my daughters is sliding down at a constant speed of 2 m/s
Use the same conditions as (a), except a rainstorm covers the TCE with 1 cm of water. Assume TCE dissolves into water and quickly reaches equilibrium with the water.
In a random pattern of eight bits used to test a micro-circuit, each bit is equally likely to be 0 or 1. Assume the values of the bits are independent.
Compute the motor size required to pump 28.3 cms through a 3,050 m long, 3.66 m diameter pipeline to an upper reservoir 610 m above the lower reservoir. Use a friction facter of 0.02 and a pump efficiency of 80 percent.
A Rankine cycle has a boiler pressure of 2500 psi and a condenser pressure of 1psi. The temperature at the inlet of the turbine is 800F. The turbine has an isentropic efficiency of 90 percent and the pump operates isentropically.
A highway reconstruction project is being undertaken to reduce crash rates. the reconstruction project involves a major realignment of the highway such that a 60mi/h design speed is attained.
Calculate the length and diameter of the reaction zone of an afterburner that treats 2000 acfm of polluted air (measured at 250 F). The gases in the afterburner are at a temperature of 1400 F for a residence time of 0.50 sec. Assume the burner will b..
The road is in good, dry conditions until 160 ft before the stalled car where it is wet and stays wet for the remaining length. What is the minimum distance from the stalled car at which the driver could apply the brakes and still stop before hitt..
question 1 ndash the pipe shaft of the auger rotating at a constant angular velocity is subject to the axial force and
A complete mix activated sludge plant operates at design Q, with the reactor tank volume set by a nominal= 6 hours.. a) It was anticipated that it would operate at 25% RAS for an expected Xr= 2,000 mg/l. What would the actual be
Determine the inclination θ of the ladder if the coefficient of static friction between the friction pad A and the ground is μs= 0.3. Assume the wall at B is smooth. The center of gravity for the man is at G.
Supporting soil has a unit weight of 125 pcf. The results of laboratory tests on the soil samples indicated that the supporting soil's cohesion and angle of internal friction are 1200 psf and 25 degrees, respectively.
