Infinite and finite potential energy well First consider an infinite one dimensional PE well of width 1 nm. Calculate the energies of the first three levels. Consider a finite PE well with the same width (1 nm). The height of the barrier is 2.0 eV. There are only three energy levels E1 0.23 eV. E2- 0.89 eV, and Es 1.81 eV. Are the finite PE well levels higher or lower than the corresponding infinite well levels? Find the electron penetration depth into the barrier for each of the three energy levels. What is your conclusions?

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.
