Water at 20 degrees flows at a velocity of (V =) 2 m/s in a (D =) 250-mm diameter horizontal ductile iron pipe. Estimate the friction factor f in the pipe, and state whether the pipe is hydraulically smooth or rough. Compare the friction factors derived from (a) the Moody diagram and (b) the Colebrook equation. Estimate the change in pressure over (L =) 100 m of pipeline. How would the friction factor and pressure change be affected if the pipe is not horizontal but 1 m lower at the downstream section?
Identical bricks 0.1m wide, and weighting 2kg are placed on a plate (assume the plate has neligible weight). Calculate the total weight (and force F required to balance the plate). How far from x=0 should F be placed so that the plate will not tip..
Assume the only products are CO2, H2O, CO and N2. State results as the CO molar fraction of both wet and dry exhaust products ( wet exhaust products include H2) and dry exhaust products exclude it).
Geometric design and construction of a new two-lane two-way road has been recently completed and now it is time for design pavement near Ballarat, Victoria.
Which software do we use to calculate force and moment, and draw shear and moment diagram? I really need this software to design my structural project. Please helps me... thank you so much.
A balloon is being inflated at the rate of 15m^3/min. At what rate is the diameter increasing after 5 min? Assume that the diameter is zero at time zero.
Determine the maximum temperature in the tank. Take the thermal conductivity of the wastes as 2.0 W/mK.
given s=.30/(60-u), where s is the spacing (space headway) in miles, and u is the speed in miles per hour, derive the relationships u-k, u-q, and q-k. Also, estmate the capacity (qmax) of the roadway.
create a primary function that uses a function handle with a nested function to compute the ninimum of the function 20x^2-200x+12 over the range 0
how kinematic and diffusion wave model been used for rainfall runoff modelling. main computer programme involved.
Estimate the required surface area (A), and the diameter and the depth of the tank.
The frame shown is used to support high-tension wires. If W = 200 lb, b = 3 ft, a = 30°, what is the axial force in member HJ?
