In a physics lab, you measure the vibrational-rotational spectrum of hcl. the estimated separation between absorption peaks is:_
1 answer:
The appropriate value in blank given is Δf = 5.5 x Hertz.
We have vibrational - rotational spectrum Hydrochloric Acid.
We have to investigate the estimated separation between absorption peaks and fill the blank.
<h3>What is vibrational - rotational spectrum ?</h3>Rotational–vibrational spectroscopy is a branch of molecular spectroscopy. It deals with the infrared and Raman spectra of molecules in the gaseous phase.
According to the question -
The estimated separation between absorption peaks in the vibrational-rotational spectrum of HCl is denoted by Δf and is equal to -
Δf = 5.5 x Hertz
Hence, the appropriate value in blank given is Δf = 5.5 x Hertz.

To solve this problem it is necessary to apply the concepts related to the adiabatic process that relate the temperature and pressure variables
Mathematically this can be determined as
Where
Temperature at inlet of turbine
Temperature at exit of turbine
Pressure at exit of turbine
Pressure at exit of turbine
The steady flow Energy equation for an open system is given as follows:
Where,
m = mass
= mass at inlet
= Mass at outlet
= Enthalpy at inlet
= Enthalpy at outlet
W = Work done
Q = Heat transferred
= Velocity at inlet
= Velocity at outlet
= Height at inlet
= Height at outlet
For the insulated system with neglecting kinetic and potential energy effects
Using the relation T-P we can find the final temperature:
From this point we can find the work done using the value of the specific heat of the air that is 1,005kJ / kgK
So:
Therefore the maximum theoretical work that could be developed by the turbine is 678.248kJ/kg
