Compression ring prevents pressurized refrigerant from blowing past the piston into the crankcase is the false statement.
Answer: Option A
<u>Explanation:</u>
Compression rings seal the combustion chamber from crankcase and then transfer heat to the cylinder from the piston. The piston rings are present in an internal combustion engine or steam engine with multi functions. The functions of piston rings are,
- Ensuring the combustion chamber is tightly sealed as to reduce the loss of gas to crankcase
.
- Promoting heat transfer from the piston to cylinder wall
.
- Controlling engine oil consumption
.
- Optimizing the proper quantity of oil between piston and cylinder wall.
Answer:
Answer to the following question is as follow.
Explanation:
Civil engineering industrial development projects have a significant influence on the environment, particularly in terms of excessive noise, environmental pollution, and land shrinkage.
Engineers have totally transformed our environment, from contemporary dwellings to bridges, space flight, automobiles, and cutting-edge mobile technologies. Engineers utilise their expertise to build new and exciting prospects and address any difficulties that may occur, and they employ their innovative ideas to accomplish so.
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

True
An organized searching process will need to start from the visual lead area. Eye focus and eye movements from the path of travel in an organized pattern describes a visual search process.
Answer:
P = $ 766.28
Explanation:
present value = ?
Future value = $ 2000
time = 5 years
compounded annually at the rate of = 10 %
2000 = P + 1.61 P
2.61 P = 2000
P = $ 766.28
hence, the present value of amount invested to get the future value of $2000 is equal to P = $ 766.28
