Lindeburg’s Practice Problem for 10th edition Chap 26; Problem no. 9(a)
Problem is asking for hardness treatment of 109 mg/l of Calcium Bicarbonate.
According to my understanding-109 mg/l as CaCO3 does not need to change it to as substance. Because
we are adding it up with CaO of 30mg/l as CaCO3.
My answer is 1200 lbm.
Lineburg's answer is 930 lbm.
Can you please clarify it for me?
Thanks in advance.
