a. The Bernoulli equation is also referred to as the mechanical energy balance. Show how the terms in the Bernoulli equation with units of m2/s2 represent units of energy. (1 mark) b. In deriving the Bernoulli equation, we defined a term called 'rate of flow work' with SI units of J/s. Starting from the equation that relates work to force and distance, derive an equation for the 'rate of flow work' in terms of pressure, density, and mass flow rate. (2 marks) c. List the two specific conditions that are required to correctly use the Blasius empirical expression to calculate the friction factor. (1 mark) d. To prevent cavitation, NPSHA must be than NPSHR. GREATER or LESS (1 mark) Name one strategy that can be used to prevent cavitation from occurring. (1 mark) e. Of the three types of blade shapes for radial flow pumps, which one is most commonly used? FORWARD-CURVED RADIAL BACKWARD-CURVED (1 mark) Briefly explain your choice of blade shape. (1 mark) f. Name any two types of forces that appear in the linear momentum equation. (1 mark)
