A basket strainer is installed in a 15-cm diameter pipe. Pressure gauges are installed immediately upstream and downstream of the basket strainer. When water flows at 100 m3/hr, the pressure gauge immediately upstream of the basket strainer measures 1 bar.
a. When the basket strainer is clean, the pressure immediately downstream measures 0.9 bar. Calculate the local loss coefficient of the clean basket strainer.
b. When the pressure drops across the basket strainer by half (i.e., to 0.5 bar after the strainer) at the 100 m3/hr flow rate, it is removed for cleaning. What is the local loss coefficient of the basket strainer at this point?
What is the most significant difference between "free" jets and flows in confined structures (nozzles, pipes, etc.) in terms of formulation of force terms ÓF(i.e. left hand side) of the momentum equation
The stream has a naturally occurring NaCl concentration of 20 mg/L. If the storm sewer flow rate is 2000 L/min and the stream flow is 2.0 m^3/s, what is the concentration of salt in the stream after the discharge point
The air above the liquid is under a pressure of 5 psig, and the specific gravity of the liquid in the tank is 0.80. If the rectangular gate is 6 ft wide and if y1 = 1 ft and y2 = 10 ft, what force P is required to hold the gate in place
Evaluate the pressure head at point a and determine the vertical effective stress at point b and evaluate the lateral pressurein the brown clay
A saturated sample of clay with an sl 20 has a natural water content of 32%. What would its dry volume be as a percentage of its original volume of Gs.= 2.67.
Water, initially dry saturated vapour at 4 bar, lls a closed rigid con- tainer. The water is heated until its temperature is 400C. Determine the work done and the heat transfer.
Explain how the different physical characteristics and moisture content of soil lead to the different angles of repose, swell, and shrinkage factors. Explain how these factors affect excavation operations and costs.
Consider a 75-ft wide overflow spillway with no piers and a design head of 18 ft. The crest elevation of the spillway is 2400 ft and the streambed elevation just upstream of the spillway is 2350 ft.
Given an 18-in. concrete conduit with a roughness coefficient of n = 0.013, s = 0.02, and a discharge capacit of 15 cfs, what diameter pipe is required to triple the capacity
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.
The fire department proposes to approach the truck from the upstream side and heavily spray the truck with water to prevent an explosion. Will this help to reduce the chlorine concentration downstream?
A grain-size analysis for a uniform sand in a loose state indicated that the soil particle diameter corresponding to 10% passing on the grain-size distribution curve is 0.18 mm. Estimate the coefficient of permeability.
