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 are smooth.
a. Air at 20 C is traveling at 3.5 m/s through a small 2-mm tube.
b. SAE-10W oil at 100 F is pumped through a 6-inch diameter pipe at 1.75ft/s.
c. Water at 20 C is sent through a small pipette of 1-mm diameter at2.5 m/s.
According to information found in an old hydraulies book, the energy loss per unit weight of fluid flowing through a nozzle connected to a hose can be estimated by the formula h=(0.04 to 0.09)(D/d)^4*V^2/2*g
What superelevation rate would you recommend for a roadway with a design speed of 100 km/hr and a radius of curvature of 500 m? Assume f = 0.11.
