Transcribed Image Text:(a) An irrigation pump can deliver 200 /min. Express this rate in megalitres per
day.
(b) Express 375,000,000 mm³ as m³.
(c) The density of water is 1 gram per cubic centimeter, what is this in kg per
cubic metre?
Conceptual activity:
In the lecture I gave a few examples highlighting the importance of units (e.g. Mars
climate orbiter being lost, and an aeroplane running out of fuel).
• For this question, you need to look up examples of either expensive mistakes, or
potentially very dangerous mistakes, which were due to incorrect units. Choose
one example to use, and it must be different to those in the lecture notes.
• Describe the scenario, why it happened, and calculate the difference in values
for SI units and the non-Sl units used.
