Consider three different processors p1, p2, and p3 executing the same instruction set. p1 has a 3 ghz clock rate and a cpi of 1.5; p2 has a 2.5 ghz clock rate and a cpi of 1.0; p3 has a 4.0 ghz clock rate and has a cpi of 2.2: a) which processor has the highest performance expressed in instructions per second? b) if the processors each execute a program in 10 seconds, find the number of cycles and the number of instructions. c) we are trying to reduce the execution time by 30% but this leads to an increase of 20% in the cpi. what clock rate should we have to get this time reduction?

Liquid flows at steady state at a rate of 2 lb/'s through a pump, which operates to raise the elevation of the liquid 100 ft from control volume inlet to exit. the liquid specific enthalpy at the inlet is 40.09 btu/lb and at the exit is 40.94 btub. the pump requires 3 btu/s of power to operate. if kinetic energy effects are negligible and gravitational acceleration is 32.174 tt/s, the heat transfer rate associated with this steady state process is most closely 1)-2,02 btu/s from the liquid to the surroundings 2)-3.98 btu/s from the surroundings to the liquid. 3)-4.96 btu/s from the surroundings to the liquid. 4)-1.04 btu/s from the liquid to the surroundings.
