Answer:
Explanation:
The functions of the following are as follows:
1). Oil Rings:
- Regulates oil within cylinder walls.
- Helps to keep cylinder walls lubricated
- Prevent Heat transfer
- Reduce friction between piston and cylinder
2). Fly Wheel:
- It is used to store rotational energy
- It resist any change in rotational speed due to its moment of inertia
- It helps to control the orientation of the mechanical system
3). Timing gears:
- It provides synchronization in the rotation of crankshaft and the camshaft so as to provide proper valve opening and closing time during each cylinder's stroke(intake and exhaust).
Answer:
The correct answer is c. object snap
Explanation:
In Autocad, the object snap is defined as a drawing aid that is used together with other different commands to help to draw accurately. It also allows snapping onto a specific object location when there is a picking point. and thus, it helps to select the center of a line.
Answer:
1.757 kg/s
Explanation:
According to the First Law of Thermodynamics
T₁ = 500⁰C
P₁ = 3.5 Mpa
T₂ = 200⁰c
P₂ = 0.3 Mpa
W = 750 kW
Q = 100KW
M = ?
using the formula
Q - W = M (h₂ - h₁)
Q = heat loss =100 kW or 100 kJ/s
W = heat generated = 750 kW or 750 kJ/s
h₂ = specific enthalpy of superheated water leaving the turbine
= Steam enters the turbine at 3.5 MPa and 500 degrees Celsius. From thermodynamic tables of superheated water, the value of the specific enthalpy is:
h₂ = h₂₀₀⁰C ,0.3 Mpa = 2967.9 kJ/kg
h₁ = specific enthalpy of superheated water entering the turbine
Similarly h₁=h₅₀₀⁰C, 3.5 Mpa = 3451.7 kJ/kg
Finally, the flow rate is calculated:
The option that is not an assumption for the Method of Joints is that
- The truss is stable
- Members are straight
- Members are weightless
<h3>
What is an assumption?</h3>
This is known to be people's believe in regard to a thing that is said to be true or maybe probably true.
Note that The option that is not an assumption for the Method of Joints is that
- The truss is stable
- Members are straight
- Members are weightless
