Bernard is a principal in a consulting engineering firm. He is also a principal owner in a construction contracting firm. In his role as consultant, Bernard prepared plans for the design of a roof structure for a wastewater treatment facility. The municipality hired a separate firm to administer the bidding and construction using the plans prepared by Bernard. In his role as owner of the construction contracting firm, Bernard thinks that bidding on the construction is a great opportunity to arrange for new employment.
1. Should Bernard bid for the project assignment? Why or why not?
2. Does Bernard have an unfair advantage over firms having designed the project on which he wants to bid?
Compute points on the velocity profile from the pipe wall to the centerline of a 3/4-in Type K copper tube if the volume flow rate of water at 60 degrees F is .50 gal/min.
Write a paper on steel sustainability.
The viscosity of the film of oil separating the piston from the cylinder is 0.020 lb.s/ft. Calculate the force required to maintain this motion.
A concrete dam retaining water has a specific weight of concrete of 23.5kn/m3, what is the factor of safety against sliding & overturning and pressure intensity on the base if coefficient of friction is 0.45
The base engine develops 200 ft-lb of torque, and a modified version of the engine develops 240 ft-lb of torque. If the overall gear reduction ratio is 8 to 1, what is the maximum acceleration from rest (in ft/sec^2) for:
A 1.50 L buffer solution is 0.250 M in HF and 0.250 M in NaF. Calculate the pH of the solution after the addition of 0.0500 moles of solid NaOH. Assume no volume change upon the addition of base. The Ka for HF is 3.5 x 10 -4 .
Cancer is the uncontrolled growth of abnormal cells in the body resulting in tumours that can be benign or malignant (cancerous cells). A proper treatment is necessary to fight with this serious disease.
What is the average length of queue, the average time spent in the system, and the average waiting time in the queue?
Determine the factors of safety against sliding and against overturning, and also the soil pressure at the heel and toe. Assume hydrostatic uplift varies uniformly from full hydrostatic head at the heel of the dam to zero at the toe. consider 1m l..
what is the final dissolved oxygen concentration (in mg/L) in the waste lagoon after all of the ammonium (NH4 + ) is converted to nitrate? Recall that 4.57 mg of O 2 is need per mg of ammonium (as N) oxidized during nitirification. After all of the..
Two particles start from the same point along the same straight line and at the same instant. The first particle travels with a constant velocity v and the second with a constant acceleration.
Assuming that the velocity variation within the main channel and the floodplain subsections is much smaller than the change in mean velocities between subsections, find the value of the kinetic energy correction coefficient.
