Water is pumped from a reservoir whose surface elevation is 1390 ft to a second reservoir whose surface elevation is 1475 ft. The connecting pipeline is 4500 ft long and 12 in. in diameter. If the pressure during pumping is 80 psi at a point midway on the pipe at elevation 1320 ft, find the rate of flow and the power exerted by the pumps. Also, plot the hydraulic grade line. Assume that f = 0.022.
The rigid bar of negligible weight is supported as shown. Find the stress in each rod if the temperature rises DeltaT after a load P is applied. Use the following data: area of steal rod 320mm2, bronze rod 1300mm2, thermal expansion coefficient Al..
Sewage flows through a 12" diameter pipeline then through an 18" diamenter pipeline. The flow is the same (unknown) value in each pipe, and the slope is the same (unknown) contant value for both pipes.
Estimate the daily emissions of sulfur dioxide, nitrogen oxides as NO2, and particulate matter from an industrial steam-generating plant equipped with a dry-bottom pulvurized-coal firing system.
design a square individual footing to support a 16 inch square reinforced concrete column. service loads include a dead load of 180 kips and a live load of 140 kips. both column and footing have fc=3000psi and fy=60000 psi.
Derive an equation for the reaction force (Rx) associated with conservation of momentum in a straight length of pipe of uniform diameter. Approximate the velocity as steady and uniform at each cross-section, and the fluid as constant density.
a 1 meter diameter cylindrical mass is connected to a 2 meter wide rectangular gate. the gate is to open when the water level drops below 2.5 meters. Determine the required value of the mass of the cylinder in kgs.
if you had a choice of three kinds of aggregate--a sandstone,a crushed basalt,and a quartizite,you may select the basalt.Give one possible characteristic or property of sanstone and of the quartzite that made you decide not to select it for your c..
Light-Voice Controlling System. We are planning to design a new light-voice controlling system. The voices will basically coordinate the crossing of a road by blind people. Suppose the crossing will be operated by two coordinated systems
A $78,000 invtestment in machinery is proposed. It is anticipated that this investment will cause a reduction in net annual operating disbursements fo $16,300 a year for 12 years. The investement will be depreciated for income tax purposes
Water with a static pressure of 1.96kN/M2 flows through an 800 mm diameter pipe. A pitot tube pressure gage in this pipe reads a pressure of 5.88 kN/M2. How do you determine the volume flow rate (Q) of the water? (Q = 1.40 M^3/sec, V=2.79 M/sec)
Could all the people in china hold back the water behind the three gorges dam?
An interesting application of the relative motion equations is the experimental determination of the speed at which rain falls. Say you perform an experiment in your car in which you park your car in the rain and measure the angle the falling rain..
