3. suppose you work for this company that evaluates boolean circuits in exponential time. since you are very smart, your manager wants you to write some code that will solve these problems in polynomial time. you have no idea of how to solve this in polynomial time. you search on the internet but do not find anything. however, your roommate tells you that he just finished writing a program called, formulaii, that solves a boolean formula in polynomial time and would let you use it. now you are in a position to write a program to solve boolean circuits in polynomial time. write high level pseudo-code.

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

Air is to be cooled in the evaporator section of a refrigerator by passing it over a bank of 0.8-cm-outer-diameter and 0.4-m-long tubes inside which the refrigerant is evaporating at -20°c. air approaches the tube bank in the normal direction at 0°c and 1 atm with a mean velocity of 4 m/s. the tubes are arranged in-line with longitudinal and transverse pitches of sl- st 1.5 cm. there are 30 rows in the flow direction with 15 tubes in each row. determine (a) the refrigeration capacity of this system and (b) pressure drop across the tube bank. evaluate the air properties at an assumed mean temperature of -5°c and 1 atm. is this a good assumption?

Determine whether or not it is possible to compress air adiabatically from k to 140 kpa and 400 k. what is the entropy change during this process?
