The floating platform shown is supported at each corner by a hollow sealed cylinder 1 m in diameter. The platform itself weights 30 kN in air, and each cylinder weighs 1.0 kN per meter of length. What total cylinder length L is required for the platform to float 1 m above the water surface? Assume that the specific weight of the water (brackish) is 10,000 N/m^3. The platform is square in plan view.
Water flows steadily through a horizontal 30 degree upward bend. The inlet diameter is 0.3 m, the velocity is 12 m/s, and the pressure is 128 kpa gage. The outlet diameter is 0.38 m and the pressure is 145 kpa gage.
At the end of the 6 years, the oil company exercised its option and bought the vessel. The chemical company has a 34% incremental tax rate. Compute its after-tax rate of return on the vessel.
A 24-in.-wide by 0.100-in.-thick by 140-in.-long steel sheet is to be formed into a hollow section by being bent through 360° and having the long edges welded (i.e., butt-welded) together. Assume a cross-sectional medial length of 24 in.
Calculate the volume of a cylinder that contains 60 lbm of carbon dioxide at 230°F and 23 psig pressure. Assume atmospheric pressure to be 14.7 psia.^4
above a peninsula of land. the length of the box is 25 km, its width is 80 km, and a radiation inversion restricts mixing to 25 m. Wind is blowing clean air into the long dimention of the box at 0.8 m/s.
Tensile tests of structural steel indicate that it fails when the axial tensile strain is 1800mu. Determine the maximum change in length that a 0:25-in diameter structural steel rod in tension can withstand before failure if it is 24 in in length
assuming that the contaminant travels mainly by advection, propose any operational changes to the given layout to prevent the river from being contaminated.
A block begins to slide down a ramp after being elevated to an angle of 47.5 degrees. What is the coefficient of static friction
A particle moves along the positive x-axis with an acceleration in meters per second squared which increases linearly with x expressed in millimeters, as shown on the graph for an interval of its motion.
Water in the amount of 1 lb is contained in a rigid closed tank. Initially the water has a quality of 0.4 at a pressure of 10 lbf/in2. Through a stirrer, work is provided to the water in the tank until the pressure quadruples.
Write a MATLAB program that loads the sensor_new.dat file. The sensor readings were actually taken every second over a period from 0 to 19 seconds. Create a time vector going from 0 to 19 in 1 second increments.
The 75 lb block is released from rest 5 ft above the plate. Determine the compression of each spring when the block momentarily comes to rest after striking the plate.
