we just ordered a cylinder of acetylene but we are concerned that it might react to form Benzene during shipment as per reaction 3C2H2=C6H6 during shipment. The pressure inside the cylinder is 50 atm and temperature is 298o K. Provide your engineering judgement (with calculations) to justify or not justify the shipment of the cylinder.
Calculate the compacted cubic yards per hour if a compactor with a 5-ft drum width travels at 3 mph over a 10-in. lift of aggregate base course with 4 passes required to meet density specifications under average operating conditions.
How much must he set aside in his savings to account for the 3-months summer to cover his rent for next year. The savings account earns 3% with monthly compounding.
If an aerial photograph is taken with this camera tilted angleA=35° at an altitude 5000ft., calculate for the ground distance of the angular coverage 60°.
The two shafts in a speed-reducer unit are subjected to couples of magnitude M1 = 18 N · m and M2 = 7.5 N · m, respectively.
If there are 50 vehicles on a 4000-ft highway lane and the average time headway between two adjacent vehicles is 2.2 seconds. A) Calculate traffic density in vehicle/mile (vpm) and average space headway in feet/vehicle (fpv).
Calculate the minimum flow rate (m^3/hr) of river water needed to acheive pre cooling hot, pasteurized liquid prodcut assuming that 10% heat is lost to the surroundings during exchange and that the water temp after cooling should not exceed 25 deg..
A reservoir discharge into a 60-inch concrete pipe (rough surface) that discharges freely. what is the pressure in the pipe at point A consider friction, but neglect minor losses.
Knowing that portion AC of the rope lies in a plane parallel to the xy plane and that the magnitude of the tension T in the rope is 62 lb, determine the moment about O of the resultant force exerted on the pulley by the rope.
Temperature is 20°C. A constriction in the pipeline causes velocity to increase to 13 m/s within the constriction. Assuming that Bernoulli's equation applies (i.e. p + ½ ? v2 = constant), is there a chance that cavitation will occur
A box of mass M=500 kg hangs by a rope from a beam with dimensions a=2.0 m and b=3.0 m. The beam has mass m=85 kg. Find the tension T_c in the cable and the magnitude of the net force F exerted on the beam by the hinge.
A train which is traveling at 80 mph applies its brakes as it reaches point A and slows down with a constant deceleration. Its decreased velocity is observed to be 60 mph as it passes a point 1/2 miles beyonds A.
A Bonda portable generator is powering a small travelling fridge (120V) in your RV and consumes 125 watts. The efficiency of the generator's gas motor is 23% and the electrical portion (power head) is more efficient at 91%.
