The centres of the piers in a bridge are 8.0m apart. The piers are each 0.8m wide. Water flow under the bridge with an upstream depth and velocity of 4.0m and 4.0m/s respectively. The pier has a drag coefficient Cd = 1.5.
a) Determine the height and the velocity of the water downstream of the bridge.
b) Determine the energy head loss.
The rate constant for decay of contaminant A in the reservoir is k=1.5 (1/year). Assuming the population, discharge rate, and reservoir conditions have been stable for a long time, estimate the concentration of A in the reservoir.
A horizontal curve on a single-lane highway has its PC at station 124 + 10 and its PI at station 131 + 40. The curve has a superelvation of 0.06 ft/ft and is designed for 70 mi/h. What is the station of the PT?

Write a MATLAB program that loads the sensor_new.dat file. The sensor readings were actually taken every second over a period from 0 to 19 seconds. Create a time vector going from 0 to 19 in 1 second increments.
a 30-acre field received 4 inches of rain with 35% runoff.Determine the volume of water infiltrated on the field ( assume all the water that doesn't runoff infiltrates )
Solar cookers can be used in less developed countries for cooking and also for thermal disinfection of water. To disinfect water, the water must be heated to about 35 Celsius for 5 hours. Of course, it takes time to raise the temperature of the wa..
Determine the air pressure at the top of a 300 m high building by assuming the density of air stays constant at the z = 0 value. Now compute the pressure assuming the density of the air varies. Is there a significant difference.
