A simply supported beam with a span of 8m is to carry, in addition to its weight, a superimposed dead load of 18kN/m and a live load of 30kN/m both over the entire span.

The beam has a rectangular section which is to be singly reinforced. Given pt=1.1% design and detail the steel reinforcement for the section where the moment is maximum

Take R=d/b=1.5, density =24kN/m3, fc=20Mpa and use N36 bars only. Exposure Classification A1 applies. use R10 bars only for closed ties maximum aggregate size=10mm

## What average speed will b have to mantain to overtake avehicle A enters the interstate and travel at 60 mph for 1/2 hour, stops for 30 mins then continues at 70 mph. If a vehicle B enters the interstate at the same location as A, |

## Determine the rainfall depths to be used for storm structureTwenty years of annual maximum rainfall depths are given below. Determine the rainfall depths to be used for storm structure design for the following annual return periods: 2, 5, 10, 25, 50, & 100 year. |

## Determine how large must lagoon be to achieve concentrationA dye mill has a highly coloured wastewater with a flow of 32 million L/day. One suggestion has been to use biological measn to treat the watewater and remove the colour, so a pilot study is performed. |

## What is the relationship between drag forces for two platesTwo different fluids flow over two identical flat plates with the same laminar free-stream velocity. Both fluids have the same viscosity, but one is twice as dense as the other. What is the relationship between the drag forces for these two plates |

## Determine the critical depth and critical velocity for flowA trapezoidal channel has a bed width of 3.5 m and a side slope of 30 degrees from the horizontal. Determine the critical depth and the critical velocity for a flow of 22 cubic meters per second. |

## Determine the required elevation drop of trapezoidal channelA clean-earth trapezoidal channel with a bottom width of 1.8 m and a side surface slope 1:1 is to drain water uniformly at a rate of 8 m^3/s to a distance ok 1 km. If the flow depth is not to exceed 1.2 m, |

## Fundamentals of hydraulic engineeringA stabilization pond is designed for a 35-day detention time. If the pond is maintained at a capacity of 40 acre-feet, what is theaverage gpd flow to the stabilizaiton pond? |

## What is the ratio of the weight of carbon emitted per yearConsider CO2 emissions from a gasoline powered vehicle. Gasoline is acomplex mixture of hydrocarbons but for the purposes of this calculation assume an average molecular formula of C7H16. |
