In an ionically bonded solid the force between two ions is given by: F= b/r^2 - c/r^10

where r is the distance between the ions, b and care constants where b= 1.2x10^-28 Nm^2 and c= 1.8x10^-105 Nm^10.

Required:
a. Identify the attractive and repulsive terms in the expression.
b. Determine the ion separation in Ã… in the solid.
c. Determine the energy in eV required to separate the ions in the solid to an infinite distance apart.

To design a steam turbine to produce 12,000 hp power. a engineer comsiders using a steady state stean low st 1160fr and engineer considers using a steady state steam flow at 1160°r and 450 psia to drive this steam turbine. the exhaust of the steam is cooled by the lake (vacuum). heat losing to the surroundings is measured at a rate of 555.55 btu/s. (a) sketch the system with the given conditions. (b) neglecting kinetic and potential energy changes from inlet to exit, determine the volumetric flow rate of the steam at the inlet, (ft'/hr). must clearly show unit conversions at crtical terms.
