What is crocco? Italian: probably from Sicilian croccu ‘hook’, hence a metonymic occupational name for a maker of hooks, crooks, and the like, or possibly a nickname for someone who wore a hook in place

## What is crocco?

Italian: probably from Sicilian croccu ‘hook’, hence a metonymic occupational name for a maker of hooks, crooks, and the like, or possibly a nickname for someone who wore a hook in place of a lost hand or arm.

**What is Crocco number?**

Crocco number is a non – dimensional fluid velocity which is defined as the ratio of fluid velocity to its maximum fluid velocity.

### What does Crocco’s theorem say about rotational flows?

Crocco’s Theorem when a steady flow field has gradients of total enthalpy and/or entropy Crocco’s theorem dramatically shows that it is rotational Explains why it is difficult to solve such problems by analytic means!

**What is energy equation fluid mechanics?**

The energy equation is a statement of the con- servation of energy principle. In fluid mechanics, it is found convenient to separate mechanical energy from thermal energy and to consider the con- version of mechanical energy to thermal energy as a result of frictional effects as mechanical energy loss.

## What is the Mach number at room temperature?

Mach number is denoted by ‘M’. Mach number ranges from zero to infinity. It falls into several flow regimes. It is 340 m/s at room temperature.

**What causes a normal shock wave?**

Normal Shock Wave Equations. As an object moves through a gas, the gas molecules are deflected around the object. But when an object moves faster than the speed of sound, and there is an abrupt decrease in the flow area, the flow process is irreversible and the entropy increases. Shock waves are generated.

### What is a energy equation?

The two equations that describe the potential energy (PE) and kinetic energy (KE) of an object are: PE = mgh. KE = ½mv² where m is the mass of the object, g is the height of the object, g is the gravitational field strength (9.8m/s²), and v is the average velocity of the object.

**What does energy equation mean?**

the law of conservation of energy

The energy equation is the mathematical formulation of the law of conservation of energy.

## How do I find my vortex strength?

The product of mass flow rate and circulation = Energy (ML2T-2). So if you have a flow with mass flow rate of X kg/s in a flow with circulation of Y m2/s, then the vortical flow has a strength equivalent to XY kgm2s-2 = XY Joules.

**What is vortex field?**

Vortex fields are said to originate from vortices. 2.1 Electric Source-Fields. Electric source-fields exist in the environment of electriC char- ges at rest (electrostatic charges, fixed or localized charges). The existence of these fields can be demonstrated via their forces on objects brought into the field.
