Consider the unit cell of the CsCl which has NaCl structure. The radius of Cs+ is 0.169 nm and that of Cl is 0.181 nm.
(a) Determine the packing factor of the structure, assuming that Cs+ and Cl− ions touch each other along the diagonals of the cube.
(b) Determine the density of CsCl if the atomic weight of Cs is 132.905 and of Cl is 35.453.

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.
