Derive an expression for efficiency of the Rankine cycle? How this cycle is different from the Carnot cycle? The Rankine cycle is the ideal cycle for vapor power plants. The ideal Rankine cycle does not have any internal irreversibility. Thermodynamic analysis of cycle : Process (4‐1): Constant pressure heat addition in a boiler. Process (1‐2): Isentropic expansion in a … [Read more...] about Efficiency of Rankine cycle
What are various Boolean identities? Draw the ‘AND’ circuit using diode logic.

What is the difference between and NAND gates? Why do we use NAND gates instead of AND gates? What is the NAND gate truth table? What is an AND gate? What is the symbol of the NAND gate? Why is it called a NAND … [Read more...] about What is the Basic Logic Gate? Describe the OR, AND, NAND gate with the help of the truth table.
What is a diode? Describe the theory of diode operation. What is the application of it? What are the types of diode? List them and draw their symbol. Diode: When a p-type semiconductor and an n-type semiconductor are joined, the device is known as a diode. It has two terminals known as electrodes, one electrode each from p‐region and n‐region hence called diode (Di + … [Read more...] about What is a diode? What is the application of it?
