For the tape of Problems 6.8 through 6.11, determine the true horizontal length of the recorded slope distance BC for the conditions shown in Problems (Assume the tape was fully supported for all measurements.)
Problem 6.8:
A 100-ft steel tape of cross-sectional area 0.0025 in.2, weight 2.3 lb, and standardized at 68°F is 99.992 ft between end marks when supported throughout under a 12-lb pull. What is the true horizontal length of a recorded distance AB for the conditions given in Problems (Assume horizontal taping and all full tape lengths except the last.)
A cylindrical chimney,1 m in diameter and 2.5 m tall is exosed to a uniform 50km/hr wind at standard atmospheric conditions.End effects and gusts may be neglected.Estimate the bending moment at the base of the chimneydue to wind force?
Determine the velocities and u and v and the speed of the flow along the streamline at (3,2). Determine the slope of the streamline in degrees from horizontal. Determine the acceleration at the point. Determine the pressure at the point (3,2) in N/m2..
An adiabatic compressor is used to bring saturated water vapor at a pressure of 103 lbf/in^2 up to 1000 lbf/in^2, where the actual exit temperatureis 1000 F. Find the compressor fficiency an the entropy generation. Is there a improvement by reducing ..

A barge has the trapeziodal shape and is 22 m long into the paper. If the total weight of barge and cargo is 350 tons, what is the draft H of the barge when floating in sea water
The probability is 1% that an electrical connector that is kept dry fails during the warranty period of a portable computer. If the connector is ever wet, the probability of a failure during the warranty period is 5%.
a community has a current population of 2800. it is estimated that in 20 years its population will be 38000. the
Fluid flows steadily, at a volume rate Q, through a large pipe and then divides into two small pipes, the larger of which has an inside diameter of 25 mm and carries three times the flow of the smaller pipe.
