14-34 A water pump is used to pump water from one large reservoir to another large reservoir that is at a higher elevation. The free surfaces of both reservoirs are exposed to atmo- spheric pressure, as sketched in Fig. P14-34. The dimen sions and minor loss coefficients are provided in the figure. The pump's performance is approximated by the expres- sion Havailable H av?, where the shutoff head H 40 m of water column, coefficient a = 0.053 m/Lpm?, available...

1. Explain why an indirect bandgap semiconductor is not considered “good” optical semiconductor. 2. Explain why a direct bandgap semiconductor is considered a “good” optical semiconductor. 3. Explain what a phonon is and explain why they are important for electron transitions between conduction and valence bands in indirect bandgap semiconductors. 4. Explain what is meant by a “radiative transition” and a “non-radiative transition” in semiconductors.

A pump delivers water at 50Cbetween reservoirs differing in elevation by 30[m]. The 0.25[m]diameter commercial steel pipe between the reservoirs is 800[m] in total length with a dis-charge side length of 712[m]. Total minor losses for the system contribute a k coefficient equal to 8. The pump characteristic curve is represented by the equation (in SI units): HP= 35.5 + 165Q−4820Q^2. 1. Compute the match point for the system (operating head and discharge). Provide a graph clearly indicating the match...

1.What process is pushing back against gravity in the very center (the core) of sun-like stars? 2."... the length of time a star spends on the main sequence is determined almost entirely by its mass with the counterintuitive result that less massive stars live longer." What is the fundamental reason why massive stars live a much shorter time than the Sun, even though they might have 30 times as much mass – and thus more fuel – available? 3.The text...
