A14 cm diameter pump at 1200 rpm has a flow rate of 1.5 m3/min and requires 2.4 kw at its best efficiency point (bep). the pump is scaled to 8 cm diameter to provide a flow rate of 0.6 m3/min at bep. determine the rotation speed and power required if the new pump is operating under similar conditions. neglect any viscous scaling effects. (select 2573 rpm)

High schoolphysics 5+3 pts a neon light consists of a glass tube with metal wires at each end. when connected to a high-voltage source, the gas glows. if a fly lands on the glass tube, what will most likely happen? a) the fly will not feel a shock because the glass conducts any free electrons back into the gas. b) electrons will flow directly from the metal wires along the glass and shock the fly. c) the fly will not feel a shock because the glass insulates it from the electrons in the gas and the metal. d) electrons that are moving through the gas will be conducted through the glass and shock the fly.
