1.a tower is surrounded by a wall that is 10 m high and 30 m away from the base of the tower. compute the length of the shortest ladder that can stand outside the wall and lean against the tower.
2.For a steel stack that exhaust 1200 m^3/min of gases at 1atm and 400 K, calculate the inner diameter if you are designing for a maximum expected wind speed at the stack of 12m/s.
3.Assume 0.1 kg of air initially at 200 kPa and 300 K undergoes an isothermal compression process to a volume of 0.02 m3. Find the work done in the process and the final pressure. Sketch the process on a P-V diagram.
The vertical post is secured by three cables. The cables are pre-tensioned so that the resultant of the cable forces F, Q, and P is directed along the z-axis. If F =120lb, find P and Q.
The difference in water level is 60ft. Determine the size of pipe for a water temperature of 60 degrees Fahrenheit. Apply The Darcy-Weisbach equation.
The grains of wood in the board make an angle of 20 degrees with the horizontal as shown. Determine the normal and shear stresses that act perpendicular and parallel to the grains if the board is subjected to an axial load of 250 N.(Dimensions l=3..
A geothermal power uses hot water (185oF) as a heat source and the cold water from a close by lake (60oF) as a heat sink. The basic operating system is a close loop ammonia efficiency of the cycle that powers turbine-driven electric generator (100..
If the river depth is larger than the subcritical sequent depth, a submerged hydraulic jump forms. Sometimes, concrete blocks called "baffle blocks" are placed on the stilling basin floor to help the hydraulic jump form within the basin.
What should be the length of an aluminum wire of 6 mm in diameter so it can be twisted one full turn without exceeding a shear stress of 42 MPa G = 27 GPa.
Calculate the concentration of oxygen in the water in equilibrium (in mg/L) with the atmosphere near La Paz, Bolivia (3650 m), at 20 degrees Celcius.
A film of newtonian liquid folws down the outside surface of avertical cylinder of radius R. the flow is steady, laminar andthe thickness of the film is constant.
Heyden Motion Solutions ordered $7 million worth of seamless tubes for its drill collars from the Timken Company of Canton, Ohio. (A drill collar is heavy tubular connection between a drill pipe and a drill bit.)
if a pipeline is horizontal, what is the porportion of the potential energy head at the upstream crossection that is changed to kinetic energy head at the downstream crossesction
Draw the shear and moment Diagram for a beam that is 10 feet long, supported on the left end by a roler, and the right end by a pin, and has a 1000 lb load placed in the center i.e at 5 feet.
