Water is contained in a piston-cylinder assembly undergoes four processes separately, all started from an initial state where th
e pressure is p1, the temperature is T1, and the specific volume is v1:
Process 1→2: Constant temperature (isothermal) to p2 = 2p1; Process 1→3: Constant specific volume to p3 = 2p1;
Process 1→4: Constant pressure (isobaric) to v4 = 2v1; Process 1→5: Constant temperature (isothermal) to v5 = 2v1.
Draw a p-v diagram and a T-v diagram for the water including the saturated liquid line and the saturated vapor line (dome).
The initial state (state 1) is at the saturated vapor state, note down state 2, 3, 4 and state 5 on both diagrams, and draw all processes (Process 1→2, 1→3, 1→4 and 1→5)
Process 1→2: Constant temperature (isothermal) to p2 = 2p1; Process 1→3: Constant specific volume to p3 = 2p1;

Answer:
The rate of fuel required to drive the air conditioner
The flow rate of the cold air is
Explanation:
From this question we are told that
The efficiency is % = 0.33
Temperature for the hot day is
Temperature after cooling is
The input power is
The rate of fuel required to drive the air conditioner can be mathematically represented as
From the question the air condition is assumed to be half as a Carnot refrigeration unit
This can be Mathematically interpreted in terms of COP(coefficient of performance) as
where denotes COP and is mathematically represented as
= >
Where is the rate of flue being burned for cold air to flow
Now if the COP of a Carnot refrigerator is having this value
Then
Now substituting the value of to solve for
The equation for the rate of fuel being burned for the cold air to flow
Making the flow rate of the cold air
Answer:
The power of force F is 115.2 W
Explanation:
Use following formula
Power = F x V
= F cos0
= (30) x 4/5
= 24N
Now Calculate V using following formula
V = + at
= 0
a = / m
a = 24N / 20 kg
a = 1.2m /
no place value in the formula of V
V = 0 + (1.2)(4)
V = 4.8 m/s
So,
Power = x V
Power = 24 x 4.8
Power = 115.2 W
Answer:
6.5 × 10¹⁵/ cm³
Explanation:
Thinking process:
The relation
With the expression Ef - Ei = 0.36 × 1.6 × 10⁻¹⁹
and ni = 1.5 × 10¹⁰
Temperature, T = 300 K
K = 1.38 × 10⁻²³
This generates N₀ = 1.654 × 10¹⁶ per cube
Now, there are 10¹⁶ per cubic centimeter
Hence,
