Question

In reaction turbines, the runner utilizes


​

Answer 1

Answer:

In computer programming, we use the if statement to control the flow of the program. For example, if a certain condition is met, then run a specific block of code. Otherwise, run another code.

For example assigning grades (A, B, C) based on percentage obtained by a student.

if the percentage is above 90, assign grade A

if the percentage is above 75, assign grade B

if the percentage is above 65, assign grade C

There are three forms of if...else statements in Java.

if statement

if...else statement

if...else if...else statement

Nested if...else statementHere, condition is a boolean expression. It returns either true or false.

if condition evaluates to true, statements inside the body of if are executed

if condition evaluates to false, statements inside the body of if are skipped

Answer 2

In reaction turbines the runner utilizes both potential and kinetic energies. As the water flows through the stationary parts of the turbine, whole of its pressure energy is not transferred to kinetic energy. When water flows through the moving parts the remaining pressure energy is converted to kinetic energy.
