By assuming a linear speed-density relationship, the mean free flow speed on a highway facility lane equals 65 mph. The jam density is observed to be about 170 vpm. 1. Plot the q-k-u curves 2. Write down the speed-density and flow-density equations 3. Find the maximum flow 4. Compute the speeds and densities corresponding to a flow rate of 1,000 vph, describing the associated traffic conditions. 5. Calculate the average headways and spacing at maximum flow and at jam density. can someone please help me plot the q-k-u curves on paper and solve remainder problems.
At a certain location during the winter, the average air temperature is 10 degrees celcius and the net radiation is 40W/m^2 and during the summer the net radiation is 200W/m^2 and the temperature is 25 degrees celcius.

Influent sample collected from a wastewater treatment plant was analyzed for various solids concentrations. Results indicated concentrations of Total Volatile Solids (TVS)
consider a spacecraft that is positioned directly between the earth and moon.the mass of the moon's is approximately 7.35 X10^22 kg, and at the instant under consideration, the moon is 3.8 X 10^8 km from earth.
Ammonium (NH4+) is a weak acid with a pKa of 9.26. The dissociation is: NH+4 NH3 + H+. Calculate the mass of ammonium added to 1 L of water in order to obtain a pH of 4 at equilibrium.
Estimate the constant rate of withdrawal (in m^3/s) from a 1375 ha reservoir in a month of 30 days during which the reservoir level dropped by 0.75 m in spite of an average inflow into the reservoir of 0.5 Mm^3/day.
A 5000 m3/day wastewater treatment plant discharges to a river with a minimum drought flow of 140 m3/min (upstream of outfall) a)What total allowable BOD (kg/day) could be discharged by the plant if the BOD in the river after initial dilution must ..
Your engineering consulting firm has been asked to determine the specific weight of an unknown material. You decide to use the concept of buoyancy to figure this out. So you weigh the material in both air and water.
A dye test reveals that the specific discharge between the two wells is about 2.75 m/day. if the wells are 45m apart, What type of aquifer material do you expect in this location
When you allow a can of carbonated beverage to sit open so that the carbon dioxide is released to the air, does the pH of beverage remain the same, increase, or decrease Why
