 Cross-sectional area of a fire hose 2008-01-27 Tom pose la question :My question is this I know the equations for the final answer but the book skips how to get to one section of the equation. Q=(a)(v) A= The cross-sectional area of the conduit in square feet (ft2). So if you have a 5 inch hose how do they get A=0.136 ft2 ? And I know the velocity already v= velocity in ft per second.Stephen La Rocque lui répond. Comparing flow rates of two pipes 2007-07-14 Kenneth pose la question :If two water pipes are 3 feet long, but one of them has a 1 foot diameter and the second has a 1 1/2 foot diameter, what simple mathematical method can be used to determine how much faster one pipe can drain water than the other pipe?Stephen La Rocque lui répond. The cross-section of a football field 2003-05-25 Francis pose la question :Have you ever walked on a football field covered with artificial turf? If so, you probably noticed that the field is not flat. The profile of the surface is arched and highest in the centre, permitting rainwater to drain away quickly. height from base to highest point- 45.75 centimetres distance of the field- 50 metres a) The diagram shows the profile of an actual field, viewed from the end of the field. Assuming that the cross-section is a parabola, find the algebraic model that describes this shape. b) Use your equation to determine the distance from the sidelines where the field surface is 20 cm above the base line. Harley Weston lui répond. Cross-sectional area of a cylinder 1999-04-12 Rebecca Connor pose la question :What is the formula to find the cross-sectional area of a cylinder?Chris Fisher lui répond.
