Nasa’s ames research center in mountain view, california has a centrifuge built to simulate high-g environments. it spins horizontally in uniform circular motion, with the payload (possibly a human! ) in a box at the end of a 29-foot arm. its maximum rotation rate is 50 revolutions per minute (rpm). (a) what is the centripetal acceleration experienced by an object in the payload box when it is spinning at its maximum rate? (b) how many gs is this acceleration, and could a human survive it (take the maximum survivable g-force to be 8g). (c) what would the rotation rate be to produce this maximum g-force of 8g?

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.
