When you are climbing a hill on a bike with different speeds, why does it seem like you are pedaling a lot to cover a short dist

ololo11 [35]

It seems like your pedaling a lot because it takes more energy and is way slower than a regular road. It you switch to the higher gear it will make you go slower because it is made for going down hill or going high speeds and a lower gear will help you more cause its easier and it will make it go faster.

Answer:

$D=0.016m$

Explanation:

From the question we are told that:

Discharge Rate $F_r=0.5kgls$

Pressure $P=15Kpa$

Temperature $T=25=>298K$

Ambient pressure is 1 atm.

Generally the equation for Density is mathematically given by

$\rho=\frac{PM}{RT}$

$\rho=\frac{15*10^5*28.0134*10^{-3}}{8.314*298}$

$\rho=16.958kg/m^2$

Generally the equation for Flow rate is mathematically given by

$F_r=\mu A\sqrt{Q \rho P(\frac{2}{Q+1})^{\frac{Q+1}{Q-1}}}$

Where

$Q=Heat coefficient\ ratio\ of\ Nitrogen$

$Q=1.4$

$\mu= Discharge\ coefficient$

$\mu=0.68$

Therefore

$0.5=0.68 A\sqrt{1.4 16.958 15*10^{5}(\frac{2}{1.4+1})^{\frac{1.4+1}{1.4-1}}}$

$A=2.129*10^{-4}$

Where

$A=\frac{\pi}{4}D^2$

$\frac{\pi}{4}D^2=2.129*10^{-4}$

$D=0.016m$
