Plot the mass flow parameter m. 0(AP0) versus the Mach number for k =1.2, 1.4, and 1.6 in the range of 0 ≤ Ma ≤ 1.
A 400ft equal-tangent sag vertical curve has its PVC at station 200 + 00 and elevation 250ft. The initial grade is -5.0% and the final grade is +2.5%. Determine the elevation of the lowest point of the curve.
Use input values of epsilon (B1), pipe radius (B2), and Reynolds number (B3) to estimate "f" and place these in the same cells . Display the final answer in a message box and round to five figures. Use a short cut key of Ctrl+g
calculate the ratio of the area to volume for unit cube,a unit sphare inscribed inside the cube,and as right cylinder inscribed inside the cube.
A piston-cylinder device contains 3 ft3 of air at 60 psia and 150°F. Heat is transferred to the air in the amount of 40 Btu as the air expands isothermally. Determine the amount of boundary work done during this process.
The following data represents, in square meters, the cross-sectional areas along a short portion of highway. Calculate the net volume of earthworks needed or available over the portion of the highway.
A rigid horiztonal bar is suspended from two springs and is subjected to a vertical force of F0 = 158.8 kips. Each spring has a stiffness k = 14.7 kips/inch. If L1 = 11 inches and L2 = 11 inches, use strain energy to calculate the deflection of th..
Suppose that the distance from the lake outlet to the withdrawal cannot be more than 20 mi. What should be the new volume of the lake?
Colette Lake has a surface area of 103 ha and a mean depth of 8 m. The pH of the water is 7.6. The lake receives surface water from a lake upstream, rainfall, and diffuse groundwater input
