Water from a lower reservoir (water surface elevation) 500 m is pumping to the upper reservoir (water surface elevation 600 m) through a 5000 m long straight pipe with 0.5 m diameter. If the flow rate is 1m3/s, calculate head supplied by the pump. Draw HGL and EGL for the system. Assume the water depth in the lower reservoir is 5 m and the depth in upper reservoir is 10m. The pump is located close to the pipe entrance at the lower reservoir.
Determine the Modulus of Elasticity of Concrete by the ACI formula for a concrete cylinder that has a unit weight of 120pcf (1920kg/m^3) and a compressive strength of 3000 psi (21MPa).
Discuss the following examples: a) Car overheating b) Personal budget deficit c) Shower too hot or too cold In all the cases discuss first the normal condition and after that the problem condition.
An engineering student, recognizing that the "ideal gas law" requires gas velocity to be function of temperature, suggests that an easy way to increase efficiency would be to change the temperature of the exhaust gas being treated.
The position of a particle moving along an x axis is given by x = 17t2 - 5.0t3, where x is in meters and t is in seconds. (a) Determine the position, velocity, and acceleration of the particle at t = 3.0 s. x = m v = m/s a = m/s2
The flow is designed using a rectangular coordinate system whose orgin is at the free surface midway between the walls. The x axis is normal to the walls, and the y axis points vertically downward.
Suppose you are told that a process must achieve a 2.7 log removal of Giardia cysts. What does that mean in terms of % remaining and % removal
Five $1,000 bonds having a bond rate of 8% per year payable quarterly are pur chased for $4,940 and kept for 6 years, at which time they are sold. Determine the selling price that yields a 6% effective annual return on the investment.
A streamlined, high-speed train travels at 200 km/hr. The flow over the train is similar to flow over a flat plate. Estimate the boundary layer thickness at the end of the train, which is 125 m long. The temperature is 10°C.
A 30-ft-high, 1-ft-diameter pipe is welded to the top of a cubic container 13 ft * 3 ft * 3 ft2. The container and pipe are filled with water at 20°C. Determine the weight of the water and the pressure forces on the bottom and sides of the contain..
rom a photograph one observes that on a level section of highway 10% of the vehicles are trucks, 90% are cars, and that there are 50 vehicles per mile of highway. The trucks travel at 40 mph, and the cars at 50 mph.
