1.A river flows towards a lake with a velocity of 3 m/s and rate of 500 m3/s at a location of 90 m above the lake surface. Determine the total power generation potential of the river at that location.
2.A fireboat draws seawater with density 1030 kg/m3 through a 20 cm diameter inlet pipe at a rate of 0.1 m3/s. It discharges through a nozzle of 5 cm diameter that is 4 m above sea level. If the head loss is 3m and the pump is 70 % efficient, what pump power is required and what is the discharge velocity.
3.A hydroelectric plant passes 8 million gal/min across a head of 600 ft. If the turbine is 80 % efficient and head loss in the system is 200 feet. What is the power output?
The total gas volume that flowed through the dry gas meter was 2.785 cubic meters (at T = 60 deg F and P = 800 mm Hg). The mass of PM (particulate matter) was 1.50 g. Also, 72.0 g of H20 was collected in impingers.
A light rail route has 2 terminals and 4 intermediate stations. The demand (passengers/hr) for morning peak hour is: North Terminal Station 1 Station 2 Station 3 Station 4 South Terminal
the weight of a sample of coarse aggregate was measured under various conditions with the following results: oven-dry weight in air 1076.3 g air-dry weight in air 1083.3 gsaturated-surface-dry weight in air 1089.2 g
What is the change in internal energy of the system? Assume the displacement work in a (fully resisted) constant pressure process is given by (*sub 12 means from stage 1 to 2) Wsub12=p(Vsub2-Vsub1).
Soil with a unit weight of 19.65 kN/m^3 is loaded on the ground surface by a strip load of 1.5 m wide. The strip load is 365 kN/m of wall length. Determine the vertical stress increment due to the strip load and the total pressure
Provide a comparative analysis of the types of safeguards would you suggest for the company's information system.
A beam that is part of a rigid frame has end moments and mid-span moments for dead, live, and earthquake loads. Determine the governing load combination for both negative and positive moments at the ends and mid-span of the beam.
The three hinged arch is composed of segments of a circle. Support points A and D are not at the same level. Determine (a) the horizontal and vertical components of reaction at A and D. (b) the shear, thrust, and moment in the arch at point C.
Consider the two-dimensional steady flow where the velocity field is given by V=Vo/L(-xi+yj) . Determine the streamlines for this flow. Plot streamlines for x> or =0
The solid compound shaft, made of three di¤erent materials, carries the two torques shown. (a) Calculate the maximum shear stress in each material. (b) Find the angle of rotation of the free end of the shaft.
Three cylinders from the same mix were tested for strenght. Cylinders A and B were cast in 4x8 molds while cylinder C was cast in a 6x12 mold. The total loads were as follows; cylinder A= 65,200 lbs., cylinder B= 68,550 lbs., cylinder C= 151,190 l..
