Question: When we designed the Rankine steam cycle in 13.3.5 we ignored the circulating waters kinetic and potential energy, having claimed earlier that they are negligible.

When we designed the Rankine steam cycle in §13.3.5 we ignored the circulating water’s kinetic and potential energy, having claimed earlier that they are negligible. Using the work per unit mass done by the turbine to set the energy scale, estimate the importance of the potential energy of the fluid if the height of the boiler is 40m? Estimate the importance of the kinetic energy if the maximum flow speed in the pipes is a few (say 5) m/s?
