5.8 a standard bod test is run using seeded dilution water. in one bottle, the waste sample is mixed with seeded dilution water giving a dilution of 1: 30. another bottle, the blank contains just seeded dilution water. both bottles begin the test with do at the saturation value of 9.2 mg/l. after five days, the bottle containing waste has do equal to 2.0 mg/l, while that containing just seeded dilution water has do equal to 8.0 mg/l. find the five day bod of the waste.
