Hot air at an average temperature of 100 degC flows through a 3 m long tube with an inside diameter of 60 mm. The temperature of

Arte-miy333 [17]

Answer:

$\dot Q = 912.017\,W$

Explanation:

The heat transfer rate due to convection is calculated by this formula:

$\dot Q = h_{air}\cdot A_{tube, in}\cdot (T_{air} - T_{tube})$

The output is determined by replacing terms:

$\dot Q = (20.1\,\frac{W}{m^{2}\cdot ^{\textdegree}C})\cdot (\pi )\cdot (0.06\,m)\cdot (3\,m)\cdot (100^{\textdegree}C-20^{\textdegree}C)$

$\dot Q = 912.017\,W$

A scale model is 4th the size of the pump. Determine the power ratio of the pump and its scale model if the ratio of the heads i

vredina [299]

Given:

size of scale model = 4(size of pump)

power ratio of pump and scale model = 5:1

Solution:

Let the diameter of scale model and pump be $d_{s}$ and $d_{p}$ respectively

and head be $H_{s}$ and $H_{p}$ respectively

Now, power, P is given as a function of head(H) and dischagre(Q)

P = $\rho gQH$ (1)

From eqn (1):

$P \propto QH$

and

$QH \propto \sqrt{H}D^{2}$

So,

$P \propto H^{\frac{3}{2}} D^{2}$

Therefore,

$\frac{P_{s}}{P_{p}}$ = $\frac{D_{s}^{2} H_{s}^{\frac{3}{2}}}{D_{p}^{2} H_{p}^{\frac{3}{2}}}$

$\frac{P_{s}}{P_{p}}$ = $\frac{1^{2}\times 5^{\frac{3}{2}}}{4^{2}\times 1^{\frac{3}{2}}}$

$\frac{P_{s}}{P_{p}}$ = $\frac{5\sqrt{5}}{16}$

${P_{s}}:{P_{p}}$ = ${5\sqrt{5}}:{16}$

4.In a hydroelectric power plant, 100 m3/s of water flows from an elevation of 120 m to a turbine, where electric power is gener

Dmitrij [34]

Answer:

The rate of irreversible loss will be "55.22 MW".

Explanation:

The given values are:

Elevation,

h = 120 m

Flow of water,

Q = 100 m³/s

Efficiency,

= 80%

i.e,

= 0.8

Efficiency turbine,

= 50 MW

Now,

Without any loss,

The power generated by turbine will be:

⇒ $P=\delta gQh$

On substituting the values, we get

⇒ $=1000\times 9.8\times 100\times 120$

⇒ $=117.72 \ MW$

Power generated in actual will be:

= $\frac{50}{0.8}$

= $62.5 \ MW$

Hence,

Throughout the piping system,

The rate of irreversible loss is:

= $Power \ generated \ by \ turbine-Power \ generated \ in \ actual$

= $117.72-62.5$

= $55.22 \ MW$

The viscosity of all liquids decreases as the temperature is a) Increased b) decreased c) maintained constant d) fluctuating e)

mars1129 [50]

Answer:

b) decreased

Explanation:

Viscosity is the measure of the resistance between the layers of the liquid. On increasing temperature, the kinetic energy of the molecules of the liquid increases which in turn increase in the random motion of the molecules. Thus, the relative motion of the molecules in the liquid become easier and hence, viscosity decreases.
