Somewhere in the Alps, a mountain lake discharges into a 8-m wide stream with boulders across the bottom and gravel along its sides, thus having a Manning coefficient n = 0.041. At the starting point on the edge of the lake, the stream bottom lies 0.90 m below the open water level in the lake and, downstream of that point, the bottom slope is uniform at S = 0.005.
(a) What is the volumetric discharge of the lake into the stream? And, for this discharge, can the bottom slope be considered mild or steep?
(b) What are the water depth and velocity at the head of the stream? And,what are they far downstream (assuming no change in slope, width or bottom
Draw circle and put line with angle inside the circle that reflected in it. Make sure the measurement is punctual for each one. Angels required are 20-40-60 degrees. that means you have to draw three circles.
When working with flow through pipes , engineers typically have to determine if the flow is laminar or turbulent. Compute the Reynolds number for each of the cases below and determine if the flow is laminar or turbulent. Assume all of the conduits..
the pressure drop over 15 m of 2-cm diameter galvanized iron pipe is measured to be 60 Pa. If the pipe is horizontal, estimate the flow rate of water. use for water v=10^-6 m^2/s and density of water = 1000kg/m^3
A vane, 10 cm long and 8 cm in diameter, was pressed into soft clay at the bottom of a bore hole. Torque was applied and gradually increased 45 N-m when failure took place. Subsequently the vane rotated rapidly so as to completely remould the soil..
The flat circular disk rotates about a vertical axis through O with a slowly increasing angular velocity. Prior to rotation, each of the 0.60-kg sliding blocks has the position x = 29 mm with no force in its attached spring.
Wet steam at a pressure of 1382 kPa and a quality of 99% is throttled to a pressure of 689.5 kPA. Find the temperature after throttling.
A core sample of basalt, 4 inches long and 2 inches in diameter, was tested in unconfined compression. The basalt is known to have a modulus of elasticity = 9.1 x 106 psi.
A thermal reservoir (T=308K) is brought in contact with the tank, transferring enough heat to the tank to raise the pressure inside to 4 bar. Calculate the entropy changes of the refrigerant and the thermal reservoir
Given an 18-in. concrete conduit with a roughness coefficient of n = 0.013, s = 0.02, and a discharge capacity of 15 cfs, what diameter pipe is required to triple the capacity?
A semicircular open channel to be made of concrete is to be designed to carry 1.5 m^3/s at a slope of 0.00085. Manning's roughness coefficient is 0.015. Determine the dimensions of the best hydraulic section.
