A hemispherical parachute made of an air-impervious material is 8.0(m) in diameter. The mass of the parachute and load combined is 80(kg). Assume the drag coefficient of 1.42 is based on frontal area facing flow and the viscosity of air is 1.8x10-5(PI). a. How fast will the parachute descend in still air assuming pressure drag dominates? b. Calculate the Reynolds number based on these two calculations and determine whether pressure drag or viscous drag dominates. c. How far would an...

Homework The history of performance automobile design and production has been characterized by trying to get more speed for less power. High power engines are heavy, require more cooling, and consume fuel at a high rate. It is therefore advantageous for a race car to have an aerodynamic body to reduce drag. This assignment will walk you through how to estimate the top speed of a car given that we know the power rating of the engine and a few...
