Answer the following questions about pumps.
(a) Referring to Figure 4.3, balance energy between positions J and 4. Solve for Hp and describe what the energy head added by the pump accomplishes physically in the system. (b) Referring to Figure 4.3, balance energy between positions 2 and 3. Solve for Hp and describe what the energy head added by the pump accomplishes. Assume the pipe diameters at 2 and 3 are the same.
(c) What concepts (first principles) are used in deriving the power input to a centrifugal pump (Equation 5.3)?
