## Determine the tsp emission rate of the power plantOn a clear summer afternoon with a wind speed of 3.20 m/s measured at 100 m elevation, the TSP (total suspended solids) concentration was found to be 1520 ug / m3 at a point 2 km downwind |

## Determine time at which collar starts to slip relative to itThe coefficient of static friction between the collar of mass m=2 kg and the bent bar is Us=0.35, and the collar is initially d=70 cm from the spin axis AB. Assuming the motion starts at t=0, determine the time at which the collar starts to to sli.. |

## Verify that there are no outliers in the sample dataThe measurements of the nominal shear strength (in kN) for a sample of 15 prestressed concrete beams are as follows: 580 400 428 825 850 875 920 550 575 750 636 360 590 735 950 |

## Explain how to show the second derivative of thetaTwo ships A and B are moving with constant speeds Va and Vb along straight intersecting courses. The navigator of ship B notes the time rates fo change of the separation distance r between the ships and the bearing angle theta. |

## Determine what is the change in water depth for one yearA pond has a surface area of 1.0 acre. A stream flows into the pond at 1.2 cubic feet per second for the entire year. The evaporation rate, also steady for the entire year, is 1 in. /month. Assume that the pond is in the shape of a cylinder. |

## Does the spring force increase or decrease and by how muchIf the temperature of the flashlight increases to 120oF, does the spring force increase or decrease and by how much. Take the casing wall to have an outer diameter of 1.5 in., thickness 0.125in.,length L = 3 in., and elastic modulus of 300ksi. |

## Estimate low-dose cancer risk from occupational inhalationthe recommended threshhold limit value ( TLV-ACGIH) air concentration for occupational exposure to water-insoluble hexavalent chromium Cr (VI) is 0.01 mg/M^3. this concentration is based on an assumption that the individual is generally healthy an.. |

## Calculate the water content and degree of saturationA particular soil has a total (moist) unit weight of 122 pcf and a dry unit weight of 101 pcf. The specific gravity of soil is 2.70. Calculate the water content and degree of saturation. |

## What is elevation of b by neglecting curvature and reactionThe line of sight of a level falls at a rate if 0.122ft/ 100 ft when the level bubble is centered. A backsight of 4.782 is taken on point A, which is at 75 ft from the level. the elevation of a is 425.238 ft. |

## What will be the surface tension effects for the tubeA water column in a glass tube is used to measure the pressure in a glass pipe. The tube is 1/4 in. in diameter how much of the water column is due to the surface tention effects |
