## Determine the minimum required vehicle frequencyA light rail route has 2 terminals and 4 intermediate stations. The demand (passengers/hr) for morning peak hour is: North Terminal Station 1 Station 2 Station 3 Station 4 South Terminal |

## Determine the interplanar spacings for the sets of planesThe atomic radius for iron has been measured to be 0.1241 nm. Determine the interplanar spacings for the (111) and (211) sets of planes |

## Calculate pressure that is eventually reached in the tankan insulated tank contains pressurized air at 2000 kPa and 30 degrees celcius. The air is allowed to escape to the atmosphere (P=95 kPa, T=30 degrees celcius) until flow ceases. Determine the final temperature in the tank. |

## Define when the oil will be free of contaminationAn oil storage area abandoned 19 yrs ago had oil spilled on the ground and saturated the soil at a concentration of 400mg/kg of soil. A recent soil sample shows a concentration of 20mg/kg. |

## Calculate the percentage of change in total volumeCalculate the percentage of change in total volume with respect to its initial volume when a specimen of this clay is completely dried from a water content of 80%. Assume that the clay remains saturated from liquid limit to shrinkage limit. |

## Determine the minimum height on the wall from hoseDetermine the minimum height on the wall to which the firefighter can project water from the hose, so that the water strikes the wall horizontally. The speed of the water at the nozzle is Vc=48ft/s. |

## What is the pm concentration in micrometers per dcsmThe total gas volume that flowed through the dry gas meter was 2.785 cubic meters (at T = 60 deg F and P = 800 mm Hg). The mass of PM (particulate matter) was 1.50 g. Also, 72.0 g of H20 was collected in impingers. |
