2.13 A pipe (inside diameter 9 cm) is being used to pump a liquid (density = 1100 kg/m³) with a maximum mass flow rate of 0.015 kg/s. An orifice plate (C = 0.61) is to be installed to measure the flow rate. However, it is desired that the pressure drop due to the orifice plate must not exceed 15 kPa. Determine the diameter of the orifice plate that will ensure that the pressure drop will remain within the stated limit.

Question
2.13 2.14 A pipe (inside diameter 9 cm) is being used to pump a liquid (density = 1100 kg/m³) with a maximum mass flow rate of 0.015 kg/s. An orifice plate (C = 0.61) is to be installed to measure the flow rate. However, it is desired that the pressure drop due to the orifice plate must not exceed 15 kPa. Determine the diameter of the orifice plate that will ensure that the pressure drop will remain within the stated limit. A capillary tube is being used to measure the viscosity of a Newtonian liquid. The tube has a 4 cm diameter and a length of 20 cm. Estimate the viscosity coefficient for the liquid if a pressure of 2.5 kPa is required to maintain a flow rate of 1 kg/s. The liquid density is 998 kg/m³.
