A large deep lake, which initially had a uniform oxygen concentration of 1 kg/m3 , has its surface concentration suddenly raised and maintained at 9 kg/m3 concentration.

a. Draw a picture of the physical process. Select a coordinate system to describe this diffusion process. Write the general form of the oxygen species continuity equation for this system.

b. Reduce the general differential equation for the mass transfer process for the transfer of oxygen into the lake without the presence of a chemical reaction.

c. Reduce the general differential equation for the mass transfer process for the transfer of oxygen into the lake occurs with the simultaneous consumption of oxygen by a first order biological reaction, ?? = −??₀.

A well-mixed lake of 105 m3 is initially contaminated with chemical at a concentration of 1 mol/m3. The chemical leaves by the outflow of 0.5 m3/s and it reacts with a rate constant of 10-2 h -1. What will be the chemical concentration after 1 and 10 days and when will 90% of the chemical have left the lake? Use a time unit of seconds.

A piston–cylinder device initially contains 2 kg water in 1 m3 at 500 kPa. The system then cools down and the volume drops to half and pressure of 300 kPa. At this state, the piston is resting on a set of stops, and the mass of the piston is such that a pressure of 500 kPa is required to move it. (a) Show the process on a P-v, T-v and P-T diagrams with respect to saturation lines and determine, (b)...

An experiment is performed in deep space with two uniform spheres, one with mass 22.0 kg and the other with mass 110.0 kg . They have equal radii, r = 0.10 mm . The spheres are released from rest with their centers a distance 37.0 mm apart. They accelerate toward each other because of their mutual gravitational attraction. You can ignore all gravitational forces other than that between the two spheres. A) When their centers are a distance 27.0 mm...
