Answer:
An opamp is an operation amplifier. It takes an input signal and amplifies it on the output side.
An ideal opamp should have infinite impedance at its input, infinite gain on the output, and zero impedance on the output
Answer:
a) The difference in mercury levels in the manometer is 2 centimeters.
b) The gage of the gas is 2.670 kilopascals.
Explanation:
a) Pressure in gases is absolute. A manometer helps to determine the hydrostatic difference between pressure of the gas () and atmospheric pressure (), both measured in pascals. A kilopascal equals 1000 pascals and 1 meter equals 100 centimeters. That is:
(1)
Where:
- Density of mercury, measured in kilograms per cubic meter.
- Gravitational acceleration, measured in meters per square second.
- Difference in mercury levels, measured in meters.
If we know that , , and , the difference in mercury levels in the manometer is:
The difference in mercury levels in the manometer is 2 centimeters.
b) The gage pressure is the difference between gas pressure and atmospheric pressure: (, )
(2)
The gage of the gas is 2.670 kilopascals.

Answer:
Merge<-function(ss1,ss2) #function declaration which accepts 2 sequences
{
z=c(ss1,ss2) #it combines to sequences
z=sort(z) #in built function to sort the sequence
return (z) # returning merged sequence to calling function
}
y <- Merge(seq(1, 50, by=3), seq(2, 30, by=2)) #invoking merge function by passing two sequences
print(y) #printing merged sequence
Explanation:
Answer:
W = - 523.425 W = -0.5234 kW
Negative sign show power input to the pump
Explanation:
By using energy balanced at state q and state 2
As it is given neglect kinetic energy and heat transfer therefore above equation rduece to
As temp remain cosntant , so enthalapy difference is givena s
from saturated water tables, for temperature 15 degree celcius specific volume of water is
putting zi =0, z2 = 15, m= 1.5 kg/s
W = - 523.425 W
Negative sign show power input to the pump
