A horizontal Venturi flow meter consists of a convergingdiverging conduit as indicated in Fig. P5.101. The diameters of cross sections (1) and (2) are 6 and 4 in. The velocity and static pressure are uniformly distributed at cross sections (1) and (2). Determine the volume flowrate (ft3 /s) through the meter if p1 p2 3 psi, the flowing fluid is oil (p 56 lbm/ft3 ), and the loss per unit mass from (1) to (2) is negligibly small.

4) We saw in class that an electron wavefunction can actually extend through a classically forbidden region of space (potential barrier) where the potential energy is higher than the electron’s kinetic energy. This process is called quantum mechanical tunneling. In the lecture notes, we plotted th e tunneling probability for an electron as a function of barrier height and width. Using...
