Suppose we want to determine how many of the bits in a twelve-bit unsigned number are equal to zero. Implement the simplest circ

timurjin [86]

Answer:

See the picture for circuit figure.

Explanation:

First load 12 bit unsigned number on shift register and apply clock tick to increment counter from LSB bit.

Logic 1 is shifted into register to ensure counter doesn't count more than 12 bits.

An 80-L vessel contains 4 kg of refrigerant-134a at a pressure of 160kPa. Determine (a) the temperature, (b) the quality, (c) th

makvit [3.9K]

Answer:

temperature -15.6 C, quality x=0.646, enthalpy h=667.20 KJ, volume of vapor phase Vg= 79.8 L

Explanation:

property table for R-134a

https://www.ohio.edu/mechanical/thermo/property_tables/R134a/R134a_PresSat.html

at 160 KPa , temperature = -15.66 C

quality x=mass of vapour/ total mass of liq-vap mixture

alternaternately: x=(v-vf)/(vg-vf)

v=total volume i.e. volume of container"80L" 80L=0.08 cubic meter

vf=vol of liquid phase vg=vol of vapor phase vf, vg values at 160Kpa

x=(0.08-0.0007437)/(0.1235-0.0007437)=0.646

enthalpy

h=hf+xhfg hf, hfg values at 160Kpa

h=hf+xhfg=31.2+0.646(209.9)=166.80 KJ/Kg

for 4Kg R-134a h=m(166.80 KJ/Kg )=667.20 KJ

volume of vapor phase

vg at 160Kpa=0.1235 cubic meter for quality=1.

in this case quality=0.646 , so it will occupy 64.6% space of the vapor phase at quality=1.

vol. of vapor phase=0.646*0.1235=0.0798 cubic meter=79.8 L

Two piezometers have been placed along the direction of flow in a confined aquifer that is 30.0 m thick. The piezometers are 280

Dafna11 [192]

Answer:

time = 224 days

Explanation:

given data

thick = 30 m

piezometers = 280 m

head between two = 1.4 m

aquifer hydraulic conductivity = 50 m

porosity = 20%

solution

we get here average pole velocity that is get by using Darcy law that is

Va = $\frac{k}{\eta } \times \frac{\Delta h}{L}$ ................1

here Va is average pole velocity and k is hydraulic conductivity and $\eta$ is porosity

here v is = $k \times \frac{dh}{dl}$ ...........2

v = 50 × $\frac{1.4}{280}$

v = 0.25 m/day

and here average linear velocity Va will be

Va = $\frac{v}{\eta }$

Va = $\frac{0.25}{0.2}$

Va = 1.25 m/day

travel time for water will be

time = $\frac{280}{1.25}$

time = 224 days

Architecture reflects multidisciplinary

vovangra [49]

Answer:

The architectural profession is multidisciplinary. ... Some of the disciplines which intervene in the design of a building are: architectural composition, structural engineering, architectural technology and energy engineering. Depending on the strategy of designing, one or more disciplines can have priority over others..

Explanation:

Hope it helps you..

Just correct me if I'm Wrong..

But, your welcome in advance..
