A student used a respirometer to determine the rate of oxygen consumption of active woodlice. Over a measurement interval of 40 minutes40\text{ minutes}40 minutes, the coloured liquid in the capillary tube was observed to move a distance of 3.6 cm3.6\text{ cm}3.6 cm.
The internal diameter of the capillary tube lumen was 0.5 mm0.5\text{ mm}0.5 mm.
The volume of a cylinder is calculated using the formula πr2l\pi r^2 lπr2l, where π=3.14\pi = 3.14π=3.14 and lll represents length.
Calculate the rate of oxygen consumption in cm3 hour−1\text{cm}^3\text{ hour}^{-1}cm3 hour−1. Show your working and give your answer to an appropriate number of significant figures.
