Determine the total mass of solids removed over the entire 8-hour period, in kg.
A bottle of medicine must be stored at a temperature between 5°C and 10°C. What does this correspond to on the Fahrenheit scale? [Note: The Fahrenheit (F) and Celsius (C) scales satisfy the relation C=(5/9)(F-32).]
A student began an experiment for the
determination of 5-day, 20°C BOD on
Monday. Since the 5th day fell on
Saturday, the final DO readings were
taken on next Monday. On calculation,
BOD (ie. 7 day, 20°C) was found to
be 150 mg/L. What would be the 5-
day, 20°C BOD (in mg/L) (up to 2
decimal value)? Assume the value of
BOD rate constant (k) at a standard
temperature of 20°C as 0,23/day (base
e).
