Explain why failure of this garden hose occurred near its end and why the tear occurred along its length. Use numerical values to explain your result. Assume the water pressure is 30 psi.
A fluid with a specific weight of 100lb/ft^3 and a negligibleviscous effects flows in a pipe. The pipe is inclined at 30degrees. Point (1) is located above point (2) in the pipe.
Assume the overall system is at steady-state, theflow rate is 15 L/min, the detention time is the PFR is 1.5 hours,and the decay rate of compound A is defined by a first-order ratereaction (k = 1 h-1).
What is the major head loss in a coarse concrete pipe with a diamter of 1ft that is 100 ft long. Water flows at a rate of 20 ft^3/s (viscosity of water = 2.344x10^-5 lbfs/ft^2, density of water = 1.94 slugs/ft^3) 1inch = 25.4mm
A layer of clay 5 m thick overlies a deposit of sand 5 m thick, which is underlain by rock. The water table in the sand is sub- artesian with a level at 2 m below ground level
Compare and contrast the two techniques of remote sensing-aerial and satellite imageries-by listing the possible uses for which each technique is appropriate. Use the comparative examples shown in Figures H.5-H.8 as a basis for your response.
Three completely mixed stabilization ponds are connected in series, and the system removes 99.998% from the total coliform count of the influent to the first pond. In stabilization ponds, coliform bacteria are removed by a first-order process
Explain the merits of the construction practice of drilling 1/8″ pilot holes into a post-tensioned concrete deck prior to drilling for 1/2″ expansion anchors. What concerns might the structural engineer have with drilling into a post-tensioned con..
determine the stations and elevations of the PVCs, PVIs and PVTs of the two vertical curves required to connect the highway segments, as well as the length of the constant grade section (connecting grade is to be small as possible).
Estimate the contact time to achieve an effluent concentration of 200 fecal coliforms/100 mL using a Cl2 dose of 3 mg/L if the wastewater temperature is 28 oC. Assume the activation energy (Ea) at pH = 7.4 is 6,500 cal/mole.
(a) determine if the flow will choke and both the downstream and upstream water depths. (b) if there is also a 1 ft high step up in bottom elevation at the contraction, determine if the flow will choke and both the downstream and upstream water de..
this concentration is based on an assumption that the individual is generally healthy and is exposed for 8 hours per day over a working lifetime ( that is from age 18 to 65 years). assuming a body weight of 78 kg and an inhalation rate of 0.63 m^3..
A solid titanium implant 280 mm long has to withstand an axial compressive force of 1200 N without buckling. If the ends can pivot (and be modeled as simply supported), determine the minimum allowable diameter before buckling can occur.
