WebDec 20, 2014 · The speed density method adopts the absolute pressure signal from intake manifold pressure sensor (MAP) and then combines the intake air temperature signal (IAT), engine speed signal, the estimated charging efficiency (CE), and the amount of exhaust gas recirculation (EGR) together and uses the speed density formula to calculate the amount … WebThe speed of sound varies greatly depending upon the medium it is traveling through. The speed of sound in a medium is determined by a combination of the medium’s rigidity (or compressibility in gases) and its density. The more rigid (or less compressible) the medium, the faster the speed of sound. flavia l. thomas doWebCheck Your Understanding. 1. A sound wave is a pressure wave; regions of high (compressions) and low pressure (rarefactions) are established as the result of the vibrations of the sound source. These compressions and rarefactions result because sound. a. is more dense than air and thus has more inertia, causing the bunching up of sound. cheems con rosas
