Toluene is being stored in a 5 m diameter cylindrical tank under a pressure of 400 kPa (absolute). The tank drains through a 2 cm diameter line located 8 m below the liquid level of the tank, you can assume that the pressure at the outlet of this line is 1 atm. Toluene has a density of 870 kg m3 and a viscosity of 0.56 mPa s. Using Bernoulli's equation (or otherwise) estimate the liquid velocity in the drain line when the valve is opened, and hence determine how long it will take for the tank to drain. Comment as to whether or not you will think the tank will actually take more or less time to drain than the value you have calculated.

A capillary tube viscometer is being selected to measure viscosity of a liquid food. The maximum viscosity to be measured will be 230 cP and the maximum flow rate that can be measured accurately is 0.015 kg/min. If the tube length is 10cm and a maximum pressure of 25 Pa can be measured, determine the tube diameter to be used. The density of the product is 1000 kg/m3.
