Isolated System:
In an Isolated system, neither energy nor masses are permitted to cross the boundary. The system has constant mass and energy. No such system exists physically. Universe is the only example that is perfectly isolated system. Other Special System
1. Adiabatic System: A system with adiabatic walls can only exchange work and not heat with the surrounding. All adiabatic systems are insulated thermally from their surroundings.
The example is Thermos flask containing a liquid.
2. Homogeneous System: A system that consists of a single phase is called as homogeneous system. For example, the mixture of air and water vapour, water added to nitric acid and octane added to heptanes.
3. Hetrogeneous System: A system, which comprises of two or more phase, is called as heterogeneous system. Example of it is Water added to steam, Ice added to water and water added to oil.
A semi circular frame of flexural rigidity EI is built at A and caries a vertical load W at B. calculate the magnitude of the vertical and horizontal deflection at B and hence the
assumptions made in deriving a bending formula

A gear drive is needed to transmit a maximum power of 22.5KW. The velocity ratio is 1:2 and r.p.m. of the pinion is 200. The centre distance between the shafts can be taken as 600m
Q. What is Precipitation? Precipitation includes rain, snow and hail. The maximum, average, and storm volumes will have an impact on the size and positioning of facilities to c
Working of Reaction turbine: In the impulse turbine the steam is expanded, causing pressure and heat drop in nozzle only and the moving blades only direct the steam through an
