How do temperature and pressure influence the rate of evaporation of water in a closed vessel?

$\frac{1}{22.4}\frac{\mathrm{mol}}{\mathrm{L}}$ is only valid for standard conditions. Use the ideal gas law to calculate the concentration for your conditions. $s \equiv$ standard conditions $2 \...

Mass Transfer from an Oxygen Bubble

Your approach is wrong because the left hand side represents the derivative of the composition of two time dependent functions. You completely ignored that fact and started cancelling terms. I try to ...

How to quantify a misty-ness of a spray?

The degree of atomization is assessed by measuring the droplet size distribution and plotting the result as a histogram. The size distribution is measured by scattering light off the cloud of spray, ...

Usage of Thermodynamic Steam Tables

You are mis-reading the tables or trying to get a value you cannot get via temperature and pressure. Your question didn't make sense to me, so I consulted my dad's Thermodynamics text book just top ...

Fully saturated liquid and vapour

In the real world, processes don't stop at exactly the right phase point. Real world processes are based on the heat transfer that actually occurs, so it will be (for example) less than 100% vapor, ...

How to calculate adiabatic air temperature loss caused by increase of humidity?

You are missing an equation of state that can be solved analytical or preprogram SRK or PR in a TI calculator when make it solve the enthalpy for you (enthalpy 1=enthalpy 2 but the phases are ...

How does placement of a pressure gauge in a tank of fluid affect the pressure readings?

Yes, If you remove mercury manometer, then the pressure measured will be $P = 120000 + \rho *9.81 * (1m)$. If you want to measure the pressure at the bottom of the vessel with the mercury manometer, ...

Force and Headloss Calculations for Three Stage Condenser

Not an expert with fluids but maybe this will help narrow down stuff- 1) Fan rpm should not be the first priority. 2) You should rather calculate the total pressure drop across your path (straight ...
