Answer:

Hybrid design - (B) It is a design based on multiple methodologies.

Explanation:

Hybrid simply means more than one. Certain times one thing can't be able to sustain the whole process for that multiple ideas are taken together and packed into one and a new design is made called hybrid design which includes properties of more than one designs.

It is simple as a child have abilities of parents as well as grandparents inherited. It is said as hybrid because it is a combination of more than one design. It helps to carry forward over what is already there and take it to the needed next level and helps to get desired successful results."

Question #8

iris [78.8K]

Problem solving is the act of orderly searching for solutions to problem

The correct option that involves approaching a problem in a new way is the option;

Creative thinking

The reasons why creative thinking is the correct option is given as follows;

Finding new ways to approach a problem, involves considering alternatives to already known approaches to the problem

Given that the options to be considered are to be options which have not been applied, then the process does not involve;

Context: Which looks at the variables that relate the problem with setting or circumstance that aid understanding of the problem

Critical thinking; Which is based on the analysis of the known facts, but the new proposals are required

Perseverance; Which involves adherence to a particular option despite delay or difficulty

However;

Creative thinking; Creative thinking involves the consideration of a situation thing or problem in a new way or by approaching a task differently than what was considered a regular approach, which involves finding an unused or imaginative approach to a problem

Therefore;

The option that involves finding new ways to approach a problem is creative thinking

H2O enters a conical nozzle, operates at a steady state, at 2 MPa, 300 oC, with the inlet velocity 30 m/s and the mass flow rate

Colt1911 [192]

Answer:

The flow velocity at outlet is approximately 37.823 meters per second.

The inlet radius of the nozzle is approximately 0.258 meters.

Explanation:

A conical nozzle is a steady state device used to increase the velocity of a fluid at the expense of pressure. By First Law of Thermodynamics, we have the energy balance of the nozzle:

Energy Balance

$\dot m \cdot \left[\left(h_{in}+\frac{v_{in}^{2}}{2} \right)-\left(h_{out}+\frac{v_{out}^{2}}{2} \right)\right]= 0$ (1)

Where:

$\dot m$ - Mass flow, in kilograms per second.

$h_{in}$ , $h_{out}$ - Specific enthalpies at inlet and outlet, in kilojoules per second.

$v_{in}, v_{out}$ - Flow speed at inlet and outlet, in meters per second.

It is recommended to use water in the form of superheated steam to avoid the appearing of corrosion issues on the nozzle. From Property Charts of water we find the missing specific enthalpies:

Inlet (Superheated steam)

$p = 2000\,kPa$

$T = 300\,^{\circ}C$

$h_{in} = 3024.2\,\frac{kJ}{kg}$

$\nu_{in} = 0.12551\,\frac{m^{3}}{kg}$

Where $\nu_{in}$ is the specific volume of water at inlet, in cubic meters per kilogram.

Outlet (Superheated steam)

$p = 600\,kPa$

$T = 160\,^{\circ}C$

$h_{out} = 2758.9\,\frac{kJ}{kg}$

If we know that $\dot m = 50\,\frac{kJ}{kg}$ , $h_{in} = 3024.2\,\frac{kJ}{kg}$ , $h_{out} = 2758.9\,\frac{kJ}{kg}$ and $v_{in} = 30\,\frac{m}{s}$ , then the flow speed at outlet is:
