Water flows through a nozzle at the end of a fire hose. If the nozzle exit velocity must be 20 m/s and the exit diameter is 40 m

m, determine the minimum flow rate that the pump must provide.

Answer:

minimum flow rate provided by pump is 0.02513 m^3/s

Explanation:

Given data:

Exit velocity of nozzle = 20m/s

Exit diameter = 40 mm

We know that flow rate Q is given as

$Q = A \times V$

where A is Area

$A =\frac{\pi}{4} \times (40\times 10^{-3})^2 = 1.256\times 10^{-3} m^2$

$Q = 1.256\times 10^{-3} \times 20 = 0.02513 m^3/s$

minimum flow rate provided by pump is 0.02513 m^3/s

Air is to be compressed so that its volume is reduced to half of its original volume if the initial pressure is 200 kPa and the

Alex_Xolod [135]

Answer:

$P_{2} = 527.803\,kPa$

Explanation:

The politropic relationship for a isentropic process is:

$\frac{P_{2}}{P_{1}} = \left(\frac{V_{1}}{V_{2}} \right)^{\gamma}$

Where $\gamma$ is the ratio of specific heats

The final pressure is:

$P_{2} = P_{1}\cdot \left(\frac{V_{1}}{V_{2}}\right)^{\gamma}$

$P_{2} = (200\,kPa)\cdot (2)^{1.4}$

$P_{2} = 527.803\,kPa$

Air is pumped from a vacuum chamber until the pressure drops to 3 torr. If the air temperature at the end of the pumping process

malfutka [58]

Answer:

The final pressure is 3.16 torr

Solution:

As per the question:

The reduced pressure after drop in it, P' = 3 torr = $3\times 0.133\ kPa$

At the end of pumping, temperature of air, $T = 5^{\circ}C = 278 K$

After the rise in the air temperature, $T' = 20^{\circ}C = 293 K$

Now, we know the ideal gas eqn:

PV = mRT

So

$P = \frac{m}{V}RT$

$P = \rho_{a}RT$ (1)

where

P = Pressure

V = Volume

$\rho_{a} = air\ density$

R = Rydberg's constant

T = Temperature

Using eqn (1):

$P = \rho_{a}RT$

$\rho_{a} = \frac{P}{RT}$

$\rho_{a} = \frac{3 times 0.133\times 10^{3}}{0.287\times 278} = 0.005 kg/m^{3}$

Now, at constant volume the final pressure, P' is given by:

$\frac{P}{T} = \frac{P'}{T'}$

$P' = \frac{P}{T}\times T'$

$P' = \frac{3}{278}\times 293 = 3.16 torr$

Which is the best description of power? A. the amount of kinetic energy lost during motion

cestrela7 [59]

Answer:

D. a measure of how fast a machine performs work

Explanation:

Power can be defined as the energy required to do work per unit time.

Mathematically, it is given by the formula;

$Power = \frac {Energy}{time}$

Hence, the best description of power is that, it is a measure of how fast a machine performs work.

This can be calculated by using the mathematical expression below;

$Power = \frac {Work done}{Time}$

But we know that, $Workdone = force * distance$
