1.An 8-inch water main with a flow rate of 14 ft3/sec raises 100-feet. At the beginning of the main the pressure is 110 psig and drops to 50-psig at the end. For this water main calculate the head loss.
2.The flow of water over a weir, can be computed by Q=5.35LH^(3/2), where Q is the volume low rate of water in cubic feet per second, L is the length of weir in feet, and H is the height of water over the weir in feet. Convert the formula so that Q is in gallons per minute and L and H are measured in inches.
A chemical is added at the beginning of a water treatment plant at a dose of 750 lb/day. The water treatment plant provides water to a community of 200,000 people and the average water consumption in the city is 110 gallons per capita per day (gpc..
A wave has a height of 1.5 m in water 5 m deep and a wave period of 6 s. Plot the horizontal component of velocity, the vertical component of acceleration, and the dynamic pressure at a point 2 m below the still water level versus time for a 6-s i..
A hydraulic jump forms in a horizontal trapezoidal channel. The base width is 4m and the side slopes are 45o. The depths upstream and downstream of the jump are 1m and 3m.
An open system Brayton cycle has a heat input of 500 kW. The pressure ratio of is 15 and the mass flow rate of air through the engine is 1 kg/s. Right before compression the temperature of the air is 273K and the pressure is 70 kPa.
There are three 18 mm diameter steel bolts that are attached to a plate. The plate can support up to a 110 KN load, and the ultimate shear stress is 360 MPa. Determine the factor of safety for the given design.
The arrival rate at a parking lot is 6 veh/ min. Vehicles start arriving at 6: 00 P. M., and when the queue reaches 36 vehicles, service begins. If company policy is that total vehicle delay should be equal to 500 veh-min, what is the departure ra..
Water is pumped at a rate of 1.57 cfs from one large open tank into another through a 6 in diameter cast iron pipe 400 ft long. The water level in the second tank is 160 ft above the level of the first tank and the discharge end of the pipe is sub..
Determine the strain components strainx, Strainy, and gammaxy, then sketch the deformed shape in the xy orientation, paying particular attention to the sign of the shear deformation.
The company would like to distribute the songs between the two CDs such that the used space on each CD is about the same. Formulate the problem as an IP, and find the optimal solution.
A 2500-lb car (CD = 0.35, Af = 25 ft^2, and ? = 0.002378 slugs/ft^3) has 14-inch-radius wheels, a drivetrain efficiency of 90%, an overall gear reduction ratio of 3.2 to 1
