A fluid of density r = 1000kg/m3 and viscosity m = 0.30pa*s flows steadily down a vertical 100 mm diameter pipe and exitsas a free jet from the lower end. Determine the maximum pressure allowed in the pipe at a location 10 m above the pipe exit if the flow is to be laminar.
Drawdown at an observation well 15m from the pumped well is 3.0 m and a drawdown at a second observation well 150 m away is 0.30 m. Find the hydraulic conductivity of the aquifer.
A large concrete channel holds a hydraulic jump in which the subcritical depth of flow is 2.5 m. If 40 percent of the specific energy in the flow is lost through the hydraulic jump, what is the specific discharge in this rectangular channel
A waste mixture contains a variety of volatile organic compounds, nonvolatile organics, metals, and sandy soil. In a vitrification treatment, a. which of these materials are likely to be retained in the resulting solid
a room is to be maintained at 72 F db. It is estimated that the inside wall surface temperature could be as low as 48 F. What maximum relative and specific humidities can be maintained without condensation on the walls
The wastewater treatment plant for Pine City discharges 1 × 105 m3/day of treated waste to the Pine River. Immediately upstream of the treatment plant, the Pine River has an ultimate CBOD of 2 mg/L and a flow of 9 × 105 m3/day.
A consolidated-undrained type of test is performed. The sample fails (shears) when the total all-around confirming pressure is 45 kpa and the total axial pressure is 97 kpa.
The 3.5-Mg engine is suspended from a spreader beam having a negligible mass and is hoisted by a crane which exerts a force of 40 kN on the hoisting cable. Determine the distance the engine is hoisted in 2.4 s, starting from rest.
An embankment for a highway 30m wide & 1.5m in a compacted thickness is to be constructed from a sandy trucked from a borrow pit. the water contenet of the sandy soil in the borrow pit is 15%& its void ratio is 0.69.
The frame shown is used to support high-tension wires. If W = 200 lb, b = 3 ft, a = 30°, what is the axial force in member HJ?
A local contractor has just bought warehouse and decided to fence in an area of 1152 square feet behind the warehouse.He plans to use the wall of the building as one of the four sides that will enclose the rectangular area.
Determine the components of displacement at 1. Take E = 200 GPa, I = 250(10^6) mm^4, A = 12(10^3) mm^2 for each member.
