In a diesel engine, the fuel is ignited by (a) spark (c) heat resulting from compressing air that is supplied for combustion (d)
-Dominant- [34]

Answer:

(c) heat resulting from compressing air that is supplied for combustion

Explanation:

In a diesel engine the combustion of the fuel takes place due to the adiabatic compression which leads to elevated temperatures in the cylinder. First the air is compressed by the piston in the cylinder which raises the temperature, then the atomized fuel is put in the cylinder causing the ignition of fuel. Diesel engines have the highest thermal efficiency.

Spark causes ignition in petroleum engine.

A heat pump designer claims to have an air-source heat pump whose coefficient of performance is 1.8 when heating a building whos
Anit [1.1K]

Answer:

The claim is valid.

Explanation:

Let assume that heat pump is reversible. The coefficient of performance for the heat pump is:

COP_{HP} = \frac{T_{H}}{T_{H}-T_{L}}

COP_{HP} = \frac{300\,K}{300\,K-260\,K}

COP_{HP} = 7.5

The claim is valid as real heat pumps have lower coefficients of performance.

A circular section of material is tested. The original specimen is 200 mm long and has a diameter of 13 mm. When loaded to its p
n200080 [17]

Answer:

modulus of elasticity = 100.45 Gpa,

proportional limit = 150.68 N/mm^2.

Explanation:

We are given the following parameters or data in the question as;

=> "The original specimen = 200 mm long and has a diameter of 13 mm."

=> "When loaded to its proportional limit, the specimen elongates by 0.3 mm."

=> " The total axial load is 20 kN"

Step one: Calculate the area

Area = π/ 4 × c^2.

Area = π/ 4 × 13^2 = 132.73 mm^2.

Step two: determine the stress induced.

stress induced = load/ area= 20 × 1000/132.73 = 150.68 N/mm^2.

Step three: determine the strain rate:

The strain rate = change in length/original length = 0.3/ 200 = 0.0015.

Step four: determine the modulus of elasticity.

modulus of elasticity = stress/strain = 150.68/0.0015 = 100453.33 N/mm^2 = 100.45 Gpa.

Step five: determine the proportional limit.

proportional limit = 20 × 1000/132.73 = 150.68 N/mm^2.
