1.A race car C is being tracked via telemetry. The on-board acclerometer records and acceleration level of -.7get+.5gen. If you know that the v at this instant is 200km/hr, what is the tracks radius of curvature at this instant?
2.A NaOH solution has pOH at 8. How much volume of this NaOH solution is needed to prepare 1 L of a NaOH solution at pOH at 9.
3.During a 5 hour storm event, the precipitation over a 230-acre area is 1.5niches. There is constant infiltration at a rate of 0.12 inches/hour and the depession storage is 17 acre-ft. Is there any runoff from the area during the storm? If so, how much runoff occurs (in cfs)? you may neglect evaporation and any other in-flow to the site during the storm.
Determine the diameter (in inches) and velocity (feet per second) of a concrete storm pipe required to carry a peak flowrate of 20 cfs at a slope of 1.0% Design the pipe to flow at 75% capacity and use a Mannings n of 0.013.
The elevation of water in well A is 300m above sea level and well B is 350m above sea level. The wells are 45m apart. A dye test reveals that the specific discharge between the two wells is about 2.75m/day.
Suppose that a person who boards the elevator on the ground floor gets off on the fifth floor. Assuming that the elevator has achieved operating speed by the time it reaches the second floor and that it is still moving at its operating speed as it..

Show that the head loss in a hydraulic jump formed in a rectangular channel may be expressed as : change in E =(y2 - y1)^3/(4y1*y2) where y1 and y2 are depth of flow before and after jump.
A hydraulic jump forms in a horizontal trapezoidal channel. The base width is 4m and the side slopes are 45o. The depths upstream and downstream of the jump are 1m and 3m.
A 2-ft diameter circular pipe has a Manning's n of 0.013 and a bed slope of 2.0 X 10^-3. What is the uniform flow rate in this pipe if it is completely full (Qf) in ft^3/s? What is the centerline uniform water depth (y0) in the channel if the flow, Q..
