So this question pertains to some process engineering homework i have, which is basically the following: I have an ODE that has the form: \frac{dh^{p}}{dt}+h^{p}+\int h^{p}=F^{p}{t} where F^{p}{t} is the unit ramp function (i.e. F^{p}{t}=0 when t<0, and is equal to t when F^{p}\geq0 So my...

Homework Statement Write down the material balance for the components A, B, C, D id this reaction takes place in a batch reactor: A+B\UpdownarrowC and C+B\UpdownarrowD The difunctional starting material (A) combines with the primary reactant (B) to form a monofunctional intermediate (C)...

I'm not sure i understand what exactly you mean, could you spell it out stepwise?

Homework Statement Consider the following two well-mixed, isothermal batch reactors for the elementary and irreversible decomposition of A to B, A\stackrel{k}{\rightarrow}2B reactor1: The reactor volume is constant (Pressure is variable) reactor2: The reactor pressure is constant (Volume is...

Homework Statement Electrons incident on a crystal suffer refraction due to an attractive potential of 15V. If the angle of incidence is 45 degrees and the electrons have an incident energy of 100eV, what is the angle of refraction? Homework Equations Snell's law...

Electrons incident on a crystal suffer refraction due to an attractive potential of 15V. If the angle of incidence is 45 degrees and the electrons have an incident energy of 100eV, what is the angle of refraction? Ok, so i know that i have to use snell's law, but I'm stuck on calculating the...

Question: For an equimolar solution of n-pentane and n-hexane, compute: a) dew-point pressure at 120 F b) bubble-point temperature at 1 atm c) the vapor fraction at 120 F and 0.9 atm, and the mole fractions of the vapor and liquid phases My attempt at a solution: I calculated the...

Air is compressed to 10 atmospheres, cooled to 25 degrees C and passed through a bed of molecular sieve that has an initial moisture content of 8 lb water/100 lb sieve. the saturation vapor pressure of water at 25C is 24 mmHg. Assume M.W of air is 30 and the height of a transfer unit is 3...
