Answer:
the pressure reading when connected a pressure gauge is 543.44 kPa
Explanation:
Given data
tank volume (V) = 400 L i.e 0.4 m³
temperature (T) = 25°C i.e. 25°C + 273 = 298 K
air mass (m) = 3 kg
atmospheric pressure = 98 kPa
To find out
pressure reading
Solution
we have find out pressure reading by gauge pressure
i.e. gauge pressure = absolute pressure - atmospheric pressure
first we find absolute pressure (p) by the ideal gas condition
i.e pV = mRT
p = mRT / V
p = ( 3 × 0.287 × 298 ) / 0.4
p = 641.44 kPa
so
gauge pressure = absolute pressure - atmospheric pressure
gauge pressure = 641.44 - 98
gauge pressure = 543.44 kPa
Answer:
no, it seems that everyone is having the same issue. If you use the app you can still find the answers and see them.
Explanation:
Answer:
Given, a = 3, r = 1/2, n = 10
%r is common ratio
%n is number of terms
%a is the first term of the series
Sum = 0;
a = 3;
r = 1/2;
for i = 0 : 1 : 10;
Sum = Sum + a * r ^ i;
end
Sum

Explanation:
The transferred energy calculations can be done using the equation:
This is when:
• power is calculated in watts (W)
• energy is calculated in joules (J)
• time is calculated in seconds (s)
it can also be calculated by utilizing the same equation but with different units:
• when energy is measured in kilowatt-hours (kWh)
• when power is measured in kilowatts (kW)
• and when time is measured in hours (h)
