The reactor, generator, and the cooling towers
Answer: 383.22K
Explanation:
L = 3m, w = 1.5m
Area A = 3 x 1.5 = 4.5m2
Q' = 750W/m2 (heat from sun) ,
& = 0.87
Q = &Q' = 0. 87x750 = 652.5W/m2
E = QA = 652.5 x 4.5 = 2936.25W
T(sur) = 300K, T(panel) = ?
Using E = §€A(T^4(panel) - T^4(sur))
§ = Stefan constant = 5.7x10^-8
€ = emmisivity = 0.85
2936.25 = 5.7x10^-8 x 0.85 x 4.5 x (T^4(panel) - 300^4)
T(panel) = 383.22K

Answer:
HB = 3.22
Explanation:
The formula to calculate the Brinell Hardness is given as follows:

where,
HB = Brinell Hardness = ?
P = Applied Load in kg = 500 kg
D = Diameter of Indenter in mm = 10 mm
d = Diameter of the indentation in mm = 1.55 mm
Therefore, using these values, we get:

<u>HB = 3.22 </u>
Answer:
Option C
A field sparrow is an animal
Explanation:
Collins and Quillian's semantic network approach likened human memory to a computer and the model arranged human knowledge into nodes that were linked in order of hierarchy. Therefore, it would be easier for human knowledge to first link sparrow to sparrow, then field sparrow, then bird and finally as an animal for this case when following the hierarchy as proposed from the model.
An injector pressure drop test to see if the injector is restricted with deposits can be done using an integer test.
<h3>What is injector strain drop?</h3>
Fuel injectors have a glide charge. This glide charge of the injector is rated at a sure strain drop throughout the injector. Meaning the injector glide is say 30#/hr at 42.five PSI. This approach that that injector will glide 30#/hr so long as the strain on the deliver side, minus the strain withinside the manifold is 42.five psiListening or Clicking Test.
Start the engine and permit it to idle. Keep the engine strolling and contact the give-up of a protracted steel screwdriver towards the gas injector. Put your ear on the alternative give up of the screwdriver. A clicking sound approaches the injector's working.
