A small nitrogen container is at Pressure P1 = 5 bar and T1 = 300 K. It's been filled from a larger nitrogen container, which is P= 10 bar and T = 300 K. The filling process ends when pressure in the small container is Pf = 10 bar. What is the temperature of the small vessel at the end of the filling process? Nitrogen can be considered ideal with Cv=5R/2, independent of temperature. Please state all assumptions

## Compute relative compaction based on modified proctor testsand cone test has been performed . The test results: intial weight of cone + sand =13.51lb, Final weight of sand cone + sand= 4.26lb, weight of sand to fill cone=2.12lb, weight of soil from hole+bucket=12.42lb, weight of bucket=1.21lb |

## Determine what is the gage pressure below the liquid surfaceA liquid has the peculiar property that its mass density increases linearly with depth according to the expression p = p_water (1+0.01d) where d is the depth below the liquid surface in meters. |

## Determine the total distance the particle travels during theThe acceleration of a particle as it moves along a straight line isgiven by a = (2t-1)m/s2 where t is in seconds. If s =1mand v =2m/s when t =0 determine the particles velocity and positionwhen t = 6s. Also determine the total distance the particle t.. |

## Find the capacity of the main channel and the lateral extentField tests have shown that the Horton equation best describes the composite roughness of the channel. Find the capacity of the main channel and the lateral extent of the floodplains for a 100-year flow of 1590m^3/s. |

## What is the maximum amount of cargo that can be carriedA small truck is to be driven down a 4% grade at 70mi/hr. The coefficient of road adhesion is 0.95, and it is known that the baking efficiency is 80% when the truck is empty and decreases by one percentage point for every 100 lb of cargo added. |

## The saturated unit weight gammasat of the sand is 200 knm3a 5 inch inside diameter well is to be placed to a total depth of 60 m in an unconfined sand aquifer. the saturated |

## Design the pins so that ledge can support doug and jeremyAssume the ledge has the dimensions shown and is attached to the building with a series of equally spaved pins around the circumference of the building. |

## Determine what is the periodic table form of the c-s-h gelThe C-S-H gel can come in a variety of chemical structure forms. If it has a cement notation form of C3 S2 H8, what is the periodic table form of this C-S-H gel. What would be the balanced equations for C3 S and C2 S when hydrated into this form |

## Estimate the final ph and the final tds of the mixtureIt has been proposed to mix a 1500 L bath containing 5% by volume of H2SO4 with a 1500 L bath containing 5% by weight of NaOH. The Specific gravity of the acid added is 1.841 and its purity is 96%. |
