Problem 58

Water flows at a rate of 0.040 m3 /s in a 0.12-m-diameter pipe that contains a sudden contraction to a 0.06-m-diameter pipe. Determine the pressure drop across the contraction section. How much of this pressure difference is due to losses and how much is due to kinetic energy changes?

Step-by-Step Solution:
Step 1 of 3

Chapter 15 Part 2:  The Steady State Approximation: o Two limiting cases:  Low pressure: When [M] is small, k2>k2[M] and rate is 2ndorder  High pressure: When [M] is large, k1[M]>k2 and rate is 1 order  Intermediates follow pseudo first-order kinetics  Effects of temperature on reaction rates: o Many reactions increase rapidly with T  Increase T by 10 degrees, rate doubles o Arrhenius equation states that rate constants depend exponentially on temperature. o k=Ae^-Ea/RT o lnk=lnA-Ea/RT o When plotted with y axis lnk and x axis 1/T, the slope is a negative linear one o Strong temperature dependence of reaction rates can be related to Maxwell-Boltzmann distribution of KE.  Fraction of molecules of energies>Ea  Potential energy surface (PES): Interaction of reactants described by a potential energy surface  Reactants approach on a reaction path.  Activation energy for forward reaction: Ea,f  Activation energy for reverse reaction: Ea,r  Change in internal energy for reaction: DeltaE=Ea,f- Ea,r  Elementary reactions always increase...
