Calculate the ratio of the drag force on a jet flying at 1190 km/h at an altitude of 7.5 km to the drag force on a prop-driven t
Bond [772]

Answer:

\frac{D_{jet}}{D_{prop}}=2.865

Explanation:

Given data

Speed of jet Vjet=1190 km/h

Speed of prop driven Vprop=595 km/h

Height of jet 7.5 km

Height of prop driven transport 3.8 km

Density of Air at height 10 km p7.8=0.53 kg/m³

Density of air at height 3.8 km p3.8=0.74 kg/m³

The drag force is given by:

D=\frac{1}{2}CpAv^2\\

The ratio between the drag force on the jet to the drag force  on prop-driven transport is then given by:

\frac{D_{jet}}{D_{prop}}=\frac{(1/2)Cp_{7.5}Av_{jet}^2}{1/2)Cp_{3.8}Av_{prop}^2} \\\frac{D_{jet}}{D_{prop}}=\frac{p_{7.5}v_{jet}^2}{p_{3.8}v_{prop}}\\\frac{D_{jet}}{D_{prop}}=\frac{(0.53)(1190)^2}{(0.74)(595)^2}\\   \frac{D_{jet}}{D_{prop}}=2.865

GuDViN [60]
<span>The Ptolemaic theory of the universe was disproved by Nicolaus Copernicus (1473–1543), letter C and followed by Johannes Kepler (1571–1630). <span>Geocentric theory suggested that the Sun and moon orbited Earth, and the rest of the planets orbited the Sun is Heliocentric theory. Heliocentric theory of Nicolaus Copernicus during the Scientific Revolution on 17th and 18th century while Geocentric theory was proposed by Ptolemy (AD 150) and Aristotle. Today, we believe more on the Heliocentric theory and it has been proven as well.</span></span> <span> </span>
