Answer:

Rotary engine was early known by the name of internal combustion engine. It convert heat from a high pressure of combustion. The main advantage of rotary engine is that it can be operate with less number of vibration. It works on the principle of converting pressure into rotating motion. In rotary engine the expansion pressure is applied on the flank rotor.

2. In the above figure, what type of cylinder arrangement is shown in the figure above?

Oduvanchick [21]

Answer:

C. Horizontal

Explanation:

The type of cylinder arrangement that is shown in the figure is "Horizontal"

The arrangement is actually horizontal which is known to be horizontally opposed engine. Such engine is known as flat engine. It's a piston engine that has the cylinders located on either side of a crankshaft. It is usually located at the central crankshaft. This type of engine has performance advantage over others.

An escalator in a shopping center is designed to move 50 people, 75 kg each, at a constant speed of 0.6 m/s at 45° slope. Determ

kramer

Answer:

$\dot E = 15602.842\,W$

Explanation:

By an adequate application of the Principle of Energy Conservation, the escalator need energy to elevate from to the bottom to the top. Hence:

$E = m_{total}\cdot g \cdot y$

An expression for power needed is found by deriving the equation with respect to time:

$\dot E = m_{total}\cdot g \cdot v_{y}$

The minimum power is found by substituting known inputs:

$\dot E = (50)\cdot (75\,kg) \cdot (9.807\,\frac{m}{s^{2}} )\cdot (0.6\,\frac{m}{s} )\cdot \sin 45^{\textdegree}$

$\dot E = 15602.842\,W$

During an unsteady-flow process, the amount of mass and energy entering a control volume must be equal to the amount of mass and

SSSSS [86.1K]

Answer:

False

Explanation: An unstable flow is a flow process where the properties of the flow is unstable, in this case the flow input and flow output are not equal.

Unstable flow is also known as transient flow process because the main properties of interest which includes the time of flow and the volume of the flow through the pipe is not the same so this type of low gives more concern to the person carrying out the study.
