What are the parameters that affect life and drag forces on an aerofoil?

Vinil7 [7]

Answer:

1.The velocity of fluid

2.Fluid properties.

3.Projected area of object(geometry of the object).

Explanation:

Drag force:

Drag force is a frictional force which offered by fluid when a object is moving in it.Drag force try to oppose the motion of object when object is moving in a medium.

Drag force given as

$F_D=\dfrac{1}{2}\rho\ A\ V^2$

So we can say that drag force depends on following properties

1.The velocity of fluid

2.Fluid properties.

3.Projected area of object(geometry of the object).

Saturated liquid-vapor mixture of water, called wet steam, in a steam line at 1500 kPa is throttled to 50 kPa and 100°C. What is

frozen [14]

Answer:

$x = 0.944$

Explanation:

Steam at outlet is an superheated steam, since $T > T_{sat}$ . From steam tables, the specific enthalpy is:

$h_{out}=2682.4\,\frac{kJ}{kg}$

The throttle valve is modelled after the First Law of Thermodynamics:

$h_{in} = h_{out}$

Hence, specific enthalpy at inlet is:

$h_{in}=2682.4\,\frac{kJ}{kg}$

The quality in the steam line is:

$x = \frac{2682.4\,\frac{kJ}{kg}-844.55\,\frac{kJ}{kg}}{2791.0\,\frac{kJ}{kg} - 844.55\,\frac{kJ}{kg} }$

$x = 0.944$
