Given four inputs: a, b, c & d, where (a, b) represents a 2-bit unsigned binary number x; and (c, d) represents a 2-bit unsigned binary number y (i. e. both x and y are in the range #0 to #3) - i. e. same as q. 2 this time, there are 4 outputs - i. e. in effect, you are building 4 separate truth tables - o3, o2, o1, o0. these correspond to the unsigned 4-bit product of the two numbers x, y e. g., if a = 1, b = 0 (i. e. x = b10 => #2); c = 1, d = 1 (i. e. y = b11 => #3); then {o3, o2, o1, o0} = {0, 1, 1, 0}, since #2 * #3 = #6. derive the boolean expressions only for columns o0 and o2

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.

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.
