1. Determine the allowable axial compressive load for a structural steel W14×132 column. The ends are pin-connected and the length is 20 ft.
2. Using the AISC column approach, compute the allowable axial compressive load for the pin-connected built-up ASTM A36 steel column shown. The length of the column is 19 ft.
air enters a compressor at 14 psia 80 f with negliible speed and is discharged at 70 psia 500 f with a speed of 500
a flow of 0.5 kgs superheated steam at 5 mpa 400c and a flow of liquid water at 5 mpa 40c are mixed. if saturated
A reaction is found to be 25 times faster at 400 K than at 300 K. Measurements of the temperature exponent yielded a value of 0.7. Calculate the activation energy of the reaction. How much faster will the reaction be at 1000 K?
A small droplet of liquid detergent, falling through air in a spray drying tower, has its diameter reduced as water evaporates from the surface. If we assume that the temperature of the liquid within the drop remains at 290 K and the dry air is at..
What is the expected pressure drop across the nozzle?
The acid digestion test left 2.595 g of fiber from a composite specimen weighing 3.697 g. The composite specimen weighs 1.636 g in water. If the specific gravity of the fiber and matrix is 2.5 and 1.2, respectively
consider liquid flow between two horizontal parallel plates flowing left to right. given that the flowrate q must
Design a square individual column footing (reinforced concrete) to support a 16-in.-square reinforced concrete tied interior column. Service loads are 200 kips dead load and 160 kips live load.
A simply-supported beam of span 2 m is subjected to a lateral uniformly distributed load of 20 kN/m which causes a maximum vertical shear force of 20 kN at each support. Determine the maximum and average vertical shear stresses within the beam over..
The tennis coach needs a better tennis ball serve for practice. This device must fire a sequence of standard tennis balls ball from one side of a standard tennis court over the net such that they land and bounce within each of three court ..
the annual cost of operating a heat pump at year-end prices is r with units of yr. the costs are expected to inflate at
