Answer:
29.31 m
Explanation:
It is given that flow rate Q =6.0 ltrs/minute 
Diameter =10 mm
So radius = 
Area of duct 
Average velocity 
The given Reynolds number is 1800 which is less than 2000 so it will be a laminar flow
So Reynolds number friction factor 
So head loss ifs given by 
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
