A column is packed with sedimentary material with K = 8.2 x 10-6 m/s. The head at the inlet of the column is 1.99 m. The head at the outlet of the column is 1.87 m. The column is 1.25 m long. What is the volumetric flux through the column? Provide your answer in units of m/s (or, equivalently, m3/m2/s).
A sewage treatment works (STW) with 4 single-stage trickling filters has become organically overloaded due to the discharge of a biodegradable industrial effluent to the STW. This is causing effluent to pond on the surface of the filters.
Determine the clean filter head loss in a filter bed composed of 0.3 m of uniform anthracite (with an average size of 1.6 mm) placed over 0.3 m of uniform sand ( with an average size of 0.5 mm)
Determine the compressive strengths of the following
A gas stream with a particulate loading of 20.0g/m^3 is passed through a 70%-efficient cyclone followed by a 95%-efficient ESP. Calculate the overall efficiency of the system.
Determine the dimensions of the box that will minimise thecosts of materials.Based on material costs alone,how many bins canthe manufacturer produce?
The level of water in a city water tower is 125ft. above the ground. The tank is kept with an air space which can be pressurized with compressed air. It is important to maintain a pressure at the bottom of the tower at 75 psig
the block has a mass of 150 kg and rests on a surface for which the coefficients of static and kinetic friction are 0.5
A piston cylinder combination contains 2 kg of air at the ambient temperature of 25C and at the unknown ambient pressure. To provide a source of cooling on this hot Florida day
The power, P, required by an agitator in a tank is a function of the following variables, diameter of the agitator, D, Frequency of the impeller rotation, w (1/s), Viscosity of liquid, u (lbss/ft^2) and the density of the liquid ,p (slugs/ft^3)
A semiautomated system has been developed as an alternative. The costs for the proposed method are $40,000 for equipment and $1.00 per manufacturing cost per unit. What is the break-even number of units per year
Design a hollow steel shaft with an inside diameter 1/3 that of the outside diameter. The shaft transmits 200 kW at a speed of 20 Hz. The allowable shearing stress is 55 MPa, and the allowable angle of twist is 1 degree per meter of length.
