A 24" pipeline carries 4cfs up a 200' tall hill. Pressure at the bottom of the hill is 30 psi. The pipe is 2000ft long. Head loss occurs at the rate of 1.5 feet per 100 ft of pipe. Find the energy ( in head ) that must added by a pump to achive a desired pressure of 35 psi at the top of the hill.
For the beam shown be low, derive the equation of motion in the ∞- and y-directions. Recall that the deformation of a bar along its axis
A Brayton cycle with a regenerator uses air as the working fluid. The air enters the compressor at 283K and 0.1 MPa. The highest temperature in the cycle is 1073K and the pressure ratio across the compressor is 8
Determine the equations of the elastic curve using the coordinates x1 and x2. EI is constant. Use the method of integration.
A company has been discharging its waste into a holding pit for a long time. For the last several years, the pit has been full and overflowing into a local river. The waste concentration has been nearly constant at 10 mg/L of the pollutant of interes..
25 mg chemical Y (log kow = 2.88) is added to a microcosm (i.e., tank) that contains 1 kg soil, 20 L water. Chemical Y has negligible volatility (very low partitioning to air). The soil is mized with water for several days until equilibrium (between ..
If you have 10 kips acting downward on a foundation and footing, 4 feet long, with uniformly distributed load acting up ward of 2.5 k/ft (soil) also 4 ft long. what are the reactions, shear forces, and bending moments at the tree critical points
A fan is to be selected to ventilate a bathroom whose dimensions are 2 m x 3 m x 3 m. The air velocity is not to exceed 8 m/s to minimize vibration and noise.
From a photograph one observs that on a level section of highway 20% of the vehicles are trucks, 80% are cars, and that there are 50 vehicles per mile of highway. The trucks travel at 40 mph, the cars at 50 mph.
What must be provided for a condensate line from the fan coil inside a walk-in freezer to keep the water from freezing? Which subcontractor is responsible for drilling and sealing the penetration through the cooler panel for the condensate line to..
The initial conditions of the helium are 7 ft^3, 80 psia, and 100 F. The helium expands reversibly according to process PV^1.5=C until the pressure reaches 15 pisa.
A piston-cylinder device contains 0.85 kg R-134a at 263K. The piston is free to move and has a mass of 12 kg and diameter of 25 cm. The atmospheric pressure is 98 kPa. Heat is added to the cylinder until the R-134 temperature = 10 o C.
Determine the deflection of a simple uniformly loaded beam by the Ritz method,using first one term, then two terms, adn finally three terms in a sine series. Why does the coefficient of sin2piex/L vanish?
