Laws of Thermodynamics
Describe all the laws of the Thermodynamics?
Expert
There exist three laws of the thermodynamics:
a) First Law: Energy can neither be created nor it is destroyed. It only changes the forms. In any of the process within an isolated system, the total energy stays the same.
b) Second Law: Whenever the two isolated systems in the detached however nearby regions of the space, each in the thermodynamic equilibrium in itself, however not in the equilibrium along with each other at first, are at some time enabled to interact, breaking the isolation which divides the two systems, and they exchange the matter or energy, they might ultimately reach the mutual thermodynamic equilibrium. Sum of the entropies of initial, isolated systems is less than or equal to the entropy of final exchanging systems. In the process of reaching a new thermodynamic equilibrium, entropy has increased.
c) Third Law: This law states that as the temperature reaches the absolute zero, entropy of the system decreases to a minimum.
(a) A plane moving at a constant velocity, V, crashes into a building as shown in figure below. Due to the design against plane crash of that building, neither major damage nor explosion occurs but the building vibrates after the crash. Assuming that the building can

Water flows at 40 m/s from the jet of area of cross-section of 0.008 m2 on to a flat plate as shown in the figure. Determine the force F normal to the plate, and also the flow rates out of the plate. Q : Define Mechanism Mechanism : The Mechanism: The mechanism is a system of moving parts which changes an input motion and force into the desired output force and motion.
Mechanism: The mechanism is a system of moving parts which changes an input motion and force into the desired output force and motion.
Safety: The specifications should state the possible abuse and misuse the product might be subjected to. Warning labels and instructions on safe operation of the product should be given. The designer can be held accountable for any accidents that migh

Quantity: The total quantity of the product predicted and, more importantly, the production rates and batch sizes needed, should be specified. This will have implications for the types of manufacturing equipment and work organization necessary. It wil
Concurrent Engineering has happened primarily as a result of the need to shorten product development times, but improving product quality and reducing product life-cycle costs are important considerations. Some companies have even gone to the extent o
You are working in a company that has developed a process to produce DNA vaccines from E.coli. After the fermentation step a lysis step is used to release the DNA from the cells resulting in a sticky mixture. You find that an aggressive cleaning solution heated to 80°C is required to
