Answer:

Put water in the cylinder then push the piston inward

Explanation:

When water is put it displaces all the air making it possible for the piston to be pulled easier and without distraction

A compressor operates at steady state with Refrigerant 134a as the working fluid. The refrigerant enters at 0.24 MPa, 0°C, with

marissa [1.9K]

Answer:

POWER INPUT = 82.989 KW

Explanation:

For pressure P =0.24 MPa and T_1 = 0 DEGREE, Enthalapy _1 = 248.89 kJ/kg

For pressure P =1 MPa and T_1 = 50 DEGREE, Enthalapy _1 = 280.19 kJ/kg

Heat loss Q = 0.05w

Inlet diameter = 3 cm

exit diamter = 1.5 cm

volume of tank will be v = area * velocity

velocity at inlet $= \frac{0.64\60 m/s}{ \frac{\pi}{4} (3\times 10^{-2})^2} = 15.09 m/s$

velocity at outlet $= \frac{0.64\60 m/s}{ \frac{\pi}{4} (1.5\times 10^{-2})^2} = 60.36 m/s$

steady flow energy equation

$E_{IN} = E_{OUT}$

$h_1 + \frac{v_1^2}{2g} +wc = h_2 + \frac{v_2^2}{2g} + 0.05wc$

$248.89 + \frac{15.09^2}{2} + wc = 280.18 + \frac{60.36^2}{2} + 0.05 wc$

solving wc = 1830.64 kJ/kg

wc in KWH

we know that $wc = \dot m wc$

$\dot m = 4.25 kg/m3 \times (0.64/60) m^3/s$

$\dot m = 0.04533 kg/s$

$wc = 0.04533 \times 1830.64 = 82.989 kW$

Steel balls 10 mm in diameter are annealed by heating to 1150 k and then slowly cooling to 450 k in an air environment for which

Darina [25.2K]

Answer:

The answer is below

Explanation:

Given that:

ρ = 800 kg/m3, c = 600 J/kg-K, k = 40 W/m-K, Initial temperature = Ti = 1150,

Environment temperature = T = 450 K, Final temperature = T∞ = 325 K

Diameter = 10 mm = 0.01 m, A = 6

The estimated time for cooling process (t) is given as:

$t=\frac{\rho dc}{hA} ln\frac{T_i-T_\infty}{T-T_infty}=\frac{7800*0.01*600}{25*6} ln\frac{1150-325}{450-325}\\ \\t=589\ s\\t=0.1635\ h$

The estimated cooling time is 589 s

Ymorist [56]

Answer:

1) a)True

b) False

2) False

2. True

4. True

5. True

Explanation:

1.a)Computers work with only two states: zero and one which is true, the language is in 1 and 0 which is called binary

b)in fuzzy logic there are range of states such as short, little tall, very tall etc...

That is false because Fuzzy logic contains also ones and zeros (Binary).

2)2. This is false because by combining the three colors we will get only

256*256*256 color and we don't get billions of colors

eg:R G B

255 0 0 -->one color

220 0 200---> one color

Due to the difficult economic times, increased global competition, demand for customization, and increased consumer sophistication, many companies have increased their investment in hiring many employees, and outsource & off shore middle managers True or False

yes this may be True because By increased global competition, demand for customization the product needs to be developed. And for development of new products we need employees, managers etc. This in-turn increases the outsourcing of offshore middle managers.

A mouse driver (software) can have a virus if its program gets infected true or False

This is True

It depends on the virus file. Some program need to be execute perfectly if it can be infected with virus. Some applications need not run because of virus files both the situations are possible.

5)Many managers were able to tackle y2k on time and saved billions. true or False;

This is True. After the year 2000, a lot of managers are able to control billions of people because many of the Top MNC's are tackled more by managers.
