Answer:

Option C: Evaluate the route for road closures

Explanation:

One of the main concern of planning a long trip is to check if there is any road closure along the journey. This is because a road closure can seriously affect route taken to reach a destination. Without proper planning and evaluation, we might risk ourselves to take a route that meet a road closure that hinder us to reach our destination.  This may cause heavy loss of the time and money  especially in a long trip.

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

The closed tank of a fire engine is partly filled with water, the air space above being under pressure. A 6 cm bore connected to
skelet666 [1.2K]

Answer:

The air pressure in the tank is 53.9 kN/m^{2}

Solution:

As per the question:

Discharge rate, Q = 20 litres/ sec = 0.02\ m^{3}/s

(Since, 1 litre = 10^{-3} m^{3})

Diameter of the bore, d = 6 cm = 0.06 m

Head loss due to friction, H_{loss} = 45 cm = 0.45\ m

Height, h_{roof} = 2.5\ m

Now,

The velocity in the bore is given by:

v = \frac{Q}{\pi (\frac{d}{2})^{2}}

v = \frac{0.02}{\pi (\frac{0.06}{2})^{2}} = 7.07\ m/s

Now, using Bernoulli's eqn:

\frac{P}{\rho g} + \frac{v^{2}}{2g} + h = k                  (1)

The velocity head is given by:

\frac{v_{roof}^{2}}{2g} = \frac{7.07^{2}}{2\times 9.8} = 2.553

Now, by using energy conservation on the surface of water on the roof and that in the tank :

\frac{P_{tank}}{\rho g} + \frac{v_{tank}^{2}}{2g} + h_{tank} = \frac{P_{roof}}{\rho g} + \frac{v_{tank}^{2}}{2g} + h_{roof} + H_{loss}

\frac{P_{tank}}{\rho g} + 0 + 0 = \0 + 2.553 + 2.5 + 0.45

P_{tank} = 5.5\times \rho \times g

P_{tank} = 5.5\times 1\times 9.8 = 53.9\ kN/m^{2}

On a ship the price gift is 24 euros .What is the difference in the price on a day when the exchange rate is £1=2378
bija089 [108]

Answer:

The answer is "\$29.7072".

Explanation:

Please find the complete question in the attachment file.

As the original prices are 24 euros, \$ 1.2378 must be multiplied by 24.  

\to 1.2378 \times 24 = \$29.7072

Therefore the new price value will be \$ 29.7072
