Two immiscible fluids are in contact. Fluid I is denser and is also well mixed. The concentration of species a is cao everywhere within this fluid and the temperature in fluid I is held constant at To. Species a diffuses through stagnant fluid II and undergoes a first order to form species b within the fluid. Assume constant properties for both phases. The reaction occurs having a rate constant of k'' and is occuring in an exothermic manner, giving deltaHr joules per mole of a reacted. The following boundary conditions apply at x=0, ca = Keqcao and T=To and at x=L, (dco/dx)=0 and (dT/dx)=0. Determine the concentration and temperature profiles for this system.
Toxic and Hazardous waste: how are they treated, safety measures, regulations in USA about hazardous waste.
A 170 kg granite rock (ρ = 2700 kg/m 3 ) is dropped into a lake. A man dives in and tries to lift the rock. Determine how much force the man needs to apply to lift it from the bottom of the lake. Do you think he can do it?
