a pipe carries 4750 LPM of crude oil at an average velocity of 2.5m/s. Estimate the inside diameter, wall thicknes and outside diameter of the pipe. The carbon steel pipe has tensile yield strength of 250 MPa. Assume safety factore of 2 and a corrosion allowance of 2mm. The maximumoperating pressure (MOP) is 55 bar.
Determine the basin dimensions (width, length, depth) for a detention time of 3 hours and a length to width ratio of 4 to 1. (use English units)
A 5000 lb truck is being used to lift a 1000 lb boulder B that is on a 200lb pallet A. Knowing the acceleration of the truck is 1ft/s^2, determine a) the horizontal force between the tires and the ground, b) the force between the boulder and the p..
On average each student produces 1 kg of carbon dioxide per day. The recommended ventilation rate of fresh air to avoid excessive carbon dioxide buildup is 8 L per second per student.
A ssume that one half of the energy incident on the collector goes to this reservoir, which, in turn, serves as a source for a heat engine. If the temperature of the atmosphere is 70 F,
hydrogen is flowing in a 50 mm diameter pipe at a mass rate of 0.01 kg/s. at section 1 the pressure is 280 kPa abs and t= 25 . what is the average velocity?
During a 108 minute long storm, the precipitation rate over a 100 acre area is 1.65 in/hr. The phi index is 0.42 in/hr. The average outflow from the area is 92 cfs during the storm. What is the value of combined detention and interception storages ..
if the subgrade has a resilient modulus of 103,500kN/m2, design a suitable pavement consisting of a granular subbase with a layer of coefficient of 0.13, a granular base layer with a layer coefficient of 0.14, and an asphalt concrete surface with ..
A bar of monel metal (length L=9 in., diameter d=0.225 in.) is loaded axially by a tensile force P. If the bar elongates by 0.0195 in., what is the decrease in diameter d What is the magnitude of the load P
The variation in the diffusion coefficient with temperature, over an appropriate range of temperature, can usually be approximated as follows: D= (D0)e^-(Q/(KT) where, Q = activation energy (eV/atom) and k = Boltzmann's constant (8.616*10-5 eV/ato..
Maintenance expenses for a bridge in west Tennessee are estimated to be $200,000 for the first eight years followed by two separate million dollar expenditures in years 12 and 18. The expected life of the bridge is thirty years.
A bridge has cylindrical piers 1 m in diameter and spaced 15 m apart. Downstream of the bridge where the flow disturbance from the piers is no longer present, the flow depth is 2.9 m and the mean velocity is 2.5 m/s.
Many years ago, well-known architect Frank Lloyd Wright designed a mile-high skyscraper, which has never been built.
