An observer standing beside a one-lane road counted in 5 minutes 20 cars traveling at 30 mph, 30 cars
traveling at 50 mph and 10 cars traveling at 60 mph.
(a) What is the space and time-mean speeds of the observed cars?
(b) What is the average headway of the cars? [
2.20 A driver is traveling at 90 mi/h down a 3%
grade on good, wet pavement. An accident
investigation team noted that braking skid marks
started 410 ft before a parked car was hit at an
estimated 45 mi/h. Ignoring air resistance, and using
theoretical stopping distance, what was the braking
efficiency of the car?
5.2 Assume that you are an observer standing at a
point along a three-lane roadway. All vehicles in lane
1 are traveling at 30 mi/h, all vehicles in lane 2 are
traveling at 45 mi/h, and all vehicles in lane 3 are
traveling at 60 mi/h. There is also a constant spacing
of 0.5 mile between vehicles. If you collect spot speed
data for all vehicles as they cross your observation
point, for 30 minutes, what will be the time-mean
speed and space-mean speed for this traffic stream?

- There are 20 cars traveling at constant speeds on a 1 mile long ring track and the cars can pass each other freely. On the track 25% of the cars are traveling at 20 mph, 50% of the cars are traveling 10 mph, and the remaining 25% of the cars are traveling at an unknown speed. It was known that the space mean speed of all the cars on the track is 20 mph. (a) What is the speed that the remaining 25% of cars are traveling at? (b) If an observer standing on the side of the track counted the number and measured the speed of all cars that passed her for one hour, what is the time-mean speed of all the cars the observer counted?

- The pumping system shown below is supposed to provide at least 250 GPM of water to the drinking trough. The outlet of the drawn tubing at the drinking water trough discharges to the atmosphere as a water jet. The outlet of the pipe is approximately 12 ft higher than the water surface of reservoir. Expected water temperature is 70ᵒF. Your objective is to select a pump and check its performance for the specified system. Your tasks include: 1. Determine total dynamic head (TDH) operating against the pump for the design flow rate. Neglect minor losses. Note that H-W is not appropriate for this water temperature, and you need to use D-W. 2. Use the TDH and Qdesign to approach a pump vendor. She provides you the attached four pump performance curves for your consideration. 3. Select the appropriate pump based on the fit of the selection point on the pump performance curves. 4. Develop the system curve. 5. Determine the pump operating point and record the system operating conditions…arrow_forward$$ 5.1 Assume that you are observing traffic in a single lane of a highway at a specific location.
