Gaseous HCI exhibits an IR absorption at 2890 cm 1due to the hydrogen chlorine stretching vibration.
(a) Calculate the force constant for the bond.
(b) Calculate the wavenumber of the absorption band for HCI assuming the force constant is the same as that calculated in part (a).
A freely (zero friction) rotating cylinder (mounted on a vertical axis) is placed on a model boat instead of a sail. The Magnus force that is created is used to power the boat. A fan is mounted on the boat to provide airflow over the cylinder.
consider nitrogen gas contained in a piston-cylinder arrangement. the cylinder diameter is 150 mm. at the initial state
a simply supported beam of length 18 ft. is subjected to a trapezoidally distributed load that has a value of 3 kipft
the manometer shown above in problem 1 above contains water and kerosene. with both tubes open to the atmosphere the
Consider a Refrigerant 22 at 0oC that is going through a phase change from the saturated liquid to saturated vapor. Using T-dS equations, calculate the entropy change between these two phases.
a refrigerant 134a at 140 kpa and -10 degree celcius is compressed by an adiabatic 16kw compressor to an exit state of
Calculate pCrO4 if the cell potential is -0.886 V.
Draw the block diagram for this system showing all necessary transfer functions. Determine the single block transfer function with Vr and QL in the input function and P as the controlled variable.
An ordinary egg can be approximated as a 5.78 cm diameter sphere. The egg is initially at a temperature of 7.9C and is dropped into boiling water at 97C. Taking the properties of the egg to be p=1020 and cp=3.32. Determine how much heat is transferre..
There are three copper blocks, A, B, and C, containing 10 kJ of energy at 600 C, 200 C, and 100C, respectively, and a fourth iron block, D, containing 10 kJ of mechanical energy. (Thus, all devices have the same amount of energy.) The surrounding tem..
