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.
