Example 4-7: Single-stage softening A water with the ionic characteristics shown in the
bar diagram below is to be softened to the minimum calcium hardness by the lime-soda
ash process. Magnesium removal is not deemed necessary.
1. Calculate the chemical requirements and solids produced in milliequivalents per liter.
2. Draw a bar diagram for the finished water.
3. For a flow of 25,000 m³/d, calculate the daily chemical requirement and the mass of
solids produced. Assume that the lime used is 90 percent pure and the soda ash is
85 percent pure.

Il Consider the capability of a process that puts pressurized grease in an aerosol can.
The design specification calls for an average of 50 pounds per square inch (psi) of
pressure in each can with an upper tolerance limit of 56psi and a lower tolerance limit of
46psi. A sample is taken from production, and it is found that the cans average 51psi with
a standard deviation of 2psi. Find the following unknowns.
1. Capability Index (Cpk)
2. Is the process capable at the 30 level?
3. What is the probability of producing a defect? Hind: use the standard normal table
as seen below.
10-kg of R-134a fill a 1.348-m3 rigid container at an initial temperature of 240oC. The container is then heated until the pressure is 200 kPa. Determine the final temperature and the initial pressure
