A town is installing a new 10" main to carry drinking water. The only section remaining to be installed is a segment through the middle of town. However, the excavators discover an archaeological site. The town decides to split the main into two sections, each looping around the site and reconnecting at the other end. The mayor decrees that "the velocity in each branch around the site shall be equal". The town lays 800 feet of 6" pipe to the north of the site and connects to the 10" main leading awayfrom town. However, the town then finds out there is no more 6" pipe. Anywhere. The only pipe available is 8" pipe. The contractor, noting that "shall" is a legally binding term when a contract is signed, must lay the proper amount of 8" pipe such that the velocity in the two branches is the same. Determine: a) the length of 8" pipe required, b)if instead, 800 feet of 8" pipe is laid parallel to the 6" pipe, the minor loss coefficient, K,for a valve that must be placed in the 8" line to exactly cause the velocities in the two pipes to balance. Assume for purposes of solving this problem that turbulent flow exists and the resistance coefficients, f, for the 6" pipe and 8' pipe are 0.023 and 0.019,respectively.
Calculate the drawdown at the well (use r which is the distance from the pumping well = 18 in) with total withdrawals from storage after (a) 1 min, (b) 1 h, (c) 1 day, (d) 1 month, and (e) 1 yr of continuous pumping, at design capacity.
a. Determine the shear and moment diagram. b. Calculate the maximum normal stress on the top of the beam, on the bottom of the beam and indicate in terms of x its location.
a temperature probe moves with the velocity 2i+2j-3k through air. the temperature of air changes as T(x,y,z,t)=(2x^2-3y+z^3)cos(at). Find the rate of change of temperature measured by the probe.
The bar under the applied force is now 2.448 meters long. Calculate the following for the bar: a) engineering stress, b) engineering strain, c) true strain, d) Young's modulus, e) What additional information would you need to calculate the true st..
The initial concentration of carbon in the metal is 0.1wt%. We first do an experiment by applying a concentration of 5%wt of carbon at the surface of a similar slab and maintaining the system at 900 K for an hour.
The rotor of an electric generator is rotating at 200 when the motor is turned off. Due to frictional effects, the angular acceleration of the rotor after the motor is turned off is α=-0.01ω rad/s^2
A round bar of 6mm diameter is made of 6061-T6 aluminum. When the bar is stretched by an axial force P, its diameter decreases by 0.450 microns. what is the magnitude of the load P
The piezometer A is located 4,000 ft south of piezometer B. Approximately 3,000 ft of piezometer B there is a river with an elevation relative to sea level of about 455 ft.
The suppliers says it would prefer to sell the company a 65% NaOH solution and the company says the water content is immaterial as long as the equivalent costs are the same including freight.
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)
A trapezoidal canal with a bottom width of 2 m, a side slope Z=1.5, and a longitudinal slope of 0.0006 conveys a flow rate of 3 m^3/s. If the water depth in section 1 is 0.78 m and in section 2
A reservoir at elevation 700 ft will supply a second reservoir at elevation 460 ft. The reservoirs are connected by 1300 ft of 24-in cast-iron pipe and 2000 ft of 20-in cast iron pipe in series. What will be the discharge delivered from the upper ..
