1.A 10-cm diameter 2000 m long pipeline connects two reservoirs open to the atmosphere. What is the discharge in the pipeline if the water surface elevation difference of the reservoirs is 50 m? Assume a smooth pipe and ? = 1.2 x 10-6 m2/s. Neglect minor losses.
2.An analysis of the record of annual peak flows for a creek indicates that a discharge of 5430 cfs has an annual exceedance probability of 0.4.
a. In how many of the next 100 years would you expect the maximum discharge to exceed 5430 cfs?
b. What is the average period of time between independent high-flow events with discharges of 5430 cfs or greater?
The "Shape Factor" of a cross-section of a beam is defined as the fully plastic strength divided by the force or moment causing first yield. Thus the Shape Factor for bending is Mp/My and similarly for shear, is Vp/Vy.
What is the submerged discharge head loss. By what percentage is this loss reduced if the provision of a draft tube increases the discharge flow area to six times the size.
a storage tank has a diameter of 80 ft, a height of 25ft and contains oil to a height of 15ft. the suction pumps, which can handle 15000bbl/d, are started, but the safety valves are clogged and a vacuum is drawn in the tank.
a stream f gas flowing at 3000 cfm has a particulate loading of 50gr/ft what is the allowable exit loading if 95 % collection efficiency is required. what is the mass of the particles collected
Assume the ledge has the dimensions shown and is attached to the building with a series of equally spaved pins around the circumference of the building.
From historical cost records, the capacity ratio exponent of a process unit is 0.5. Use the capacity ratios raised to an exponent method to determine the estimated cost of a similar process unit with a capacity of 310 ft3/hr.
The backfill soil's unit weight and angle of internal friction are 17.2 kN/cubic meter and 31 degrees respectively and the angle of wall friction friction between backfill and wall is 20 degrees. Find the total active earth pressure against the wa..
What is the terminal settling velocity of a particle with a specific gravity of 1.4 and a diameter of 0.01 mm in 20 degrees celcius water. What is the smallest diameter particle of specific gravity 1.4
assume hydrostatic uplift varies uniformly from full hydrostatic head at the heel of the dam to zero at the toe. consider 1m length of dam.
A rectangular channel leading from an upstream lake has a bottom width of 20 ft, bottom slope of 0.0002, a Manning roughness factor of 0.016, a discharge of 403 cfs, and normal depth of 6.24 ft. Then at the downstream end the flow depth is 4.915 ft. ..
