Find the rate v with which helium flows ...

Find the rate `v` with which helium flows out of a thermally insulated vessel into vacuum through a small hole. The flow rate of the gas inside the vessel is assumed to be negligible under these conditions. The temperature of helium in the vessel is `T = 1.000 K`.

Text Solution

Verified by Experts

The correct Answer is:
`v=sqrt((2gama RT)/(gamma-1)M))=3.3xx10^(3)m//s`

Two vessels A and B of equal volume (V_0) are connected by a narrow tube which can be closed by a value. The vessels are fitted with piston which can be moved to change the volumes. Initially, the valve is open and the vessels contain an ideal gas (C_p / C_v = gamma ) at atomspheric pressures (P_0) and atmoshpeheric temperature (T_0) . The walls of the vessels A are diathermic and those of B are adiabatic.

A vessel containing one gram -mole of oxygen is enclosed in a thermally insulated vessel. The vessel is next moved with a constant speed v_(0) and then suddenly stopped. The process results in a rise in the temperature of the gas by 1^(@)c . Calculate the speed v_(0) .

Two adiabatic vessels, each containing the same mass m of water but at different temperatures, are connected by a rod of length L, cross-section A, and thermal conductivity K. the ends of the rod are inserted into the vessels, while the rest of the rod is insulated so that .there is negligible loss of heat into the atmosphere. The specific heat capacity of water is s, while that of the rod is negligible. The temperature difference between the two vessels reduces to l//e of its original value after a time, delta t . The thermal conductivity (K) of the rod may be expressed by:

In the figure shown, water flows into the open vessel through pipe A at a constant rate. The water can flow out of the vessel by pipe B. The maximum flow-rate fo the water in pipe B is slightly more than that in pipe A. Final height of the water level in the vessel would be
