Cache block size (b) can affect both miss rate and miss latency. assuming a machine with a base cpi of 1, and an average of 1.35 references (both instruction and data) per instruction, find the block size that minimizes the total miss latency given the ollowing miss rates for various block sizes.

8: 4% 16: 3% 32: 2% 63: 1.5% 128: 1%
a.) what is the optimal block size for a miss latency of 20 × b cycles?

b.) what is the optimal block size for a miss latency of 24 + b cycles?

c.) for constant miss latency, wha
t is the optimal block size?

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.

Fluids at rest possess no flow energy. a)- true b)- false

Thermal stresses are developed in a metal when its a) initial temperature is changed b) final temperature is changed c) density is changed d) thermal deformation is prevented e) expansion is prevented f) contraction is prevented
