Answer:

18.722 ft

Explanation:

The elevation difference between the PVT and a point on the curve at station

111 + 00

attached below is a detailed solution to the problem

Δelevation ( elevation difference )

= Yt - Y

= 19.355 - 0.632 = 18.722 ft

Answer:

The weather conditions do not suggest a blizzard. It is explained below.

Explanation:

wind_speed=randi([12 56],24,1);

visibility=randi([1 10],24,1)/10;

storm_data=[wind_speed,visibility];

save stormtrack.dat storm_data -ascii

clear

load stormtrack.dat

fprintf('Below is the storm data from the file stormtrack.dat \n');

disp(stormtrack)

wind_speed=stormtrack(:,1);

visibility=stormtrack(:,2);

L=length(wind_speed);

count=0;

i=0;

while count<4 && i<L

i=i+1;

if wind_speed(i)>=30 && visibility(i)<=0.5

count=count+1;

else

count=0;

end

end

if count==4

fprintf('The weather conditions suggest a blizzard.\n')

else

fprintf('The weather conditions do not suggest a blizzard.\n')

end

Results:

Below is the storm data from the file stormtrack.dat

The water level in a tank z1, is 20 m above the ground. A hose is connected to the bottom of the tank, and the nozzle at the end
Alika [10]

Answer:

the maximum height h to which the the water steam could rise is 40.65m

Explanation:

Given;

Z_{1} = 20m,

P_{1gage} = 2atm ≈ 20265 N/m

Density of water ρ = 1000 kg/m^{2}

Note: we take point 1 at the free surface of the water in the tank and point 2 at the top of the water trajectory. we also take reference level at the bottom of the tank.

fluid velocity at the free surface of tank is very low (V_{1} ≅ 0) and at the top of the water trajectory V_{2} = 0

Step 1: Applying Bernoulli equation between poin 1 and point 2

P_{1}/ρg + V_{1} ^{2}/2g + Z_{1} = P_{2}/ρg + V_{2} ^{2}/2g + Z_{2}

P_{1}/ρg + Z_{1} = P_{atm}/ρg + Z_{2}

Z_{2} = (P_{1} - P_{atm})/ρg + Z_{1}

Substituting values into Z_{2} we have,

Z_{2} = \frac{2atm}{(1000 kg/m^{3} )(9.81 m/s^{2} )} (\frac{101325N/m^{2} }{1atm} )(\frac{1 kg.m/s^{2} }{1N} ) + 20 = 40.65 m
