Answer:
. Heat transfer can be higher if themal efficiency is lower.
Explanation:
The heat transfer rate to the river water is calculated by this expression:
The actual heat transfer can be higher if the steam power plant reports an thermal efficiency lower than expected.
Answer:
<h2>The answer is FALSE</h2>
Explanation:
Brittle material are materials that don not undergo plastic deformation, they have very low plasticity that is while cracks can form without plastic deformation
The major/ common examples are glass, ceramics, graphite
In other words brittle materials break instead of bending, they have very low energy absorption as they don not undergo plastic deformation
Sleeve scale Micrometer features are given below.
Explanation:
Measurements taken with micrometer are a combination of the value shown on the sleeve scale and the value indicated on the rotating sleeve scale.
- The value of the first significant figure of a measurement can be found on the sleeve scale.
- This will be the number immediately to the left of the thimble.
-
On a metric micrometer, this will be given in millimetres. Each minor increment on the sleeve scale represents 0.5mm.
-
In this example, the reading on the sleeve scale is 6.5mm.
- Each number on the sleeve of the micrometer represents 5 millimeters (mm) or 0.005 meter (m).
- Each of the 10 equal spaces between each number, with index lines alternating above and below the horizontal line, represents 0.5mm or five-tenths of a mm.. One revolution of the thimble changes the reading one space on the sleeve scale or 0.5 mm.
- The beveled edge of the thimble is divided into 50 equal divisions with every fifth line numbered: 0, 5, 10,5. Since one complete revolution of the thimble advances the spindle 0.5mm, each graduation on the thimble is equal to one hundredth of a millimeter.
- As with the inch-graduated micrometer, the three separate readings are added together to obtain the total reading.
Answer:
Explanation:
Brooding can simply defined as. “Application of heat to the birds at early part of their life”. Brooding is the care of young chicks by provision of optimum environment. The temperature by external heat source provided until the chicks not become able to regulate its body temperature efficiently.09-May-2018
