Simulate the system to look at the output response with a unit step input applied i.e. use the
step command. Confirm the values of K and τau from the simulated response are the same as
those you have entered into the simulation. Note that the step command can be used with...
windows audio is at max.
and after checking carefully, i cans till hear the hum from the integrated speakers on the laptop. so its not an external problem. its just because the external speakers are louder.
Hi, when i plug my speakers into my laptop, i can hear a slight whining sound from one of the speakers. i assumed it was the speakers, however i plugged some brand new headphones in, and the same problem occurred. this leaves me to believe it is a problem with the laptop. does anyone know why it...
In an air compressor air flows steadily at a rate of 15 kg per minute. The air
enters the compressor at 5 m/s with a pressure of 1 bar and a specific volume
of 0.5 m3/kg. The air leaves the compressor at 7.5 m/s with a pressure of 7
bar and a specific volume of 0.15...
Oh i see, use pv = nRT to work out n.
ok, so from n = PV/RT, am i right in assuming the values of p, V and T are the differences?
n = pV/RT so n = (2850000 x 3)/(8.314 x 35)
n = 29382.45
m = nM so m = 851150.9
Im sure this is wrong as it seems too large.
A vessel of capacity 3 m3 contains air at a pressure of 1.5 bar and a
temperature of 25o C. Additional air is now pumped into the system until the
pressure rises to 30 bar and temperature rises to 60o C. The molar mass of air
is 28.968 g/mol.
