The segments of pipe and couplings used for drilling an oil well 15,000 ft deep are made of A-36 steel weighing 20 lb/ft. They have an outside diameter of 5.50 in. and an inside diameter of 4.75 in. Determine the force P needed to remove the pipe, excluding friction along its sides and requiring F = 0. Also, what is the elongation of the pipe as it just begins to come out?
Determine the maximum grade on which passenger car A can travel without its total resistance exceeding that of car B traveling on a straight and level section of road.
Design the ramp for the highest design speed (to the nearest 5 mph) without exceeding a minimum D of 8.0. (Assume the PC of the horizontal curve is at station 15+00, and the vertical curve PVIs are at the PC and PT of the horizontal curve). Maximu..
an engineering student is driving on a level roadway and sees a construction sign 180 m ahead in the middle of the
An unconfined compression test was conducted on a compacted soil sample, 50 mm diameter by 100 mm long. The peak axial force recorded was 230 N and the sample shortened by 2 mm.
Determine the minimum horizontal force P required to hold the crate from sliding down the plane. The crate has a mass of 70kg and the coefficient of static friction between the crate and the plane is μs = 0.45.
The phase diagram of a typical simple substance contains three phases , liquid vapor and solid separated by boundaries . The critical point terminates the liquid-vapor transition, in water it is at Pc=220.9 bar and Tc=374 degres celcius
Processing begins when the lane reaches capacity, what is the uniform deterministic arrival rate if the vehicle queue is cleared in 35 minutes after vehicles begin to arrive (in veh/min.)?
Solve the problem using the Darcy Weisbach equation and the Colebrook-White equation. Size the pipe to the nearest inch. Assume the water temp is 80 degrees F.
A differential leveling loop started and closed on BM Juno, elevation 5194.02 ft. The BS and FS distancces were kept approximately equal. Readings (in ft) listed in the order takken are 9.65, 2.11, 2.51, 8.35, 2.06, 9.25, 7.93, 2.83, 5.05, and 4.6..
A freeway exit ramp has a single lane and consists entirely of a horizontal curve with a central angle of 90 degrees and a length of 628 ft. If the distance cleared from the centerline for sight distance is 19.4 ft
The reaction between 2-methyl-2-pentanol and HBr to yield 2-methyl-2-pentene is probably: A) an E1-type reaction involving the protonated alcohol as the substrate. B) an SN2-type reaction involving the protonated alcohol as the substrate.
The level of one reservoir is 500 ft above the level of the other, and water is flowing steadily through the pipe from one reservoir to the other.
