An architect needs to pump 2.3 lbm/s of water to the top of the empire state building, which is about 1000 ft high. assume water at 45 psia is available at the base of the building. what is the power of the pump needed, in hp, if the flow is assumed frictionless? the velocity of the water is constant.

An electron moves with a constant horizontal velocity of 3.0 × 106 m/s and no initial vertical velocity as it enters a deflector inside a tv tube. the electron strikes the screen after traveling 26 cm horizontally and 19 cm vertically upward with no horizontal acceleration. what is the constant vertical acceleration provided by the deflector? (the effects of gravity can be ignored.)
