An 8-in-diameter pipeline (f=0.028) 500 ft long discharges a 3-in-diameter water jet into the atmosphere at a point that is 250 ft below the water surface at intake. The entrance to the pipe is reentrant, with ke = 0.9, and the nozzle loss coefficient is 0.045. Find the flow rate and the pressure head at the base of (entrance to) the nozzle.
A hollow circular shaft is loaded in pure torsion. Describe how the shear stress due to the applied torque varies on a cross section whose unit normal vector lies parallel to the long axis of the shaft.
Calculate the pressure, and the piezometric head at the free surface, at both interfaces, and at the tank bottom. Take the elevation datum at the bottom of the tank.
The shift in the oxygen-hemoglobin dissociation curve with pH and PCO2 provides more oxygen available to tissues. As an example, consider the oxygen uptake by muscle tissue. The blood flow rate is 1 L/min under resting conditions.
What will be the value of the vertical stress at this point immediately after the fill is placed, before any consolidation has occurred. What will it be after consolidation is completed.
Alternative R has a first cost of $100,000, annual M&O costs of $50,000, and a $20,000 salvage value after 5 years. Alternative S has a first cost of $175,000 and a $40,000 salvage value after 5 years
A wastewater treatment plant has two rectangular primary settling tanks, each 40 ft long, 12 ft wide, and 7 ft deep. The effulent weir length in each tank is 45 ft. The average daily wastewater flow is 387,000 gal.
The 1.2-Mg mine car is being pulled by winch M mounted on the car. If the winch generates a constant power output of 30 kW, and the car starts from rest, determine the speed of the car when t = 5s.
Find the expanded depth of the bed after the backwash when initial depth of the bed is 3 ft using given conditions. μ = 0.01g/cm/sec, T = 25oC, ρs = 2.65, ρ=1, washrate = 1.5 cm/sec, ks2 = 196. (Assumed single size)
Compute the 50 year flood discharge on a large creek in Northern Ohio if the total discharge area is 75 mi^2. The average soil infiltration is 0.5 in./hr; the main channel slope is 0.008.
Long Line: the slope distance and zenith angle measured from point a to point b were 17,685.20 ftand 93degrees 13' 46" . The instrument and reflector heights were equal. If the elevation of the point A is 1854.43 ft above the MSL Datum
if the resultant of the 1000 lb vertical force and the tensile force T in the cable is to be in the direction of the boom OB, what must be the magnitude of T
A simple curve has a central angle of 42 degreess. A point Y is located 24m from the vertex and has a perpendicular distance of 3.00m from the back tangent.
