An ideal vapor-compression heat pump cycle using R-134a is used to heat a house. The insidetemperature is 22°C, the outside temp
erature is 0°C. Saturated vapor at 2.2 bar enters thecompressor, saturated liquid leaves the condenser at 8 bar. The mass flow rate is 0.2 kg/s.
Calculate:
(a) the power input to the compressor, in kW.
(b) the coefficient of performance.

Answer:
a. 0.28
Explanation:
Given that
porosity =30%
hydraulic gradient = 0.0014
hydraulic conductivity = 6.9 x 10⁻4 m/s
We know that average linear velocity given as
The velocity in m/d ( 1 m/s =86400 m/d)
v= 0.27 m/d
So the nearest answer is 'a'.
a. 0.28

See explanation
Explanation:
The multiplicity of a root of a polynomial equation is the number of times the root repeats.
Let be the root of
, then;
has a multiplicity of 1.
has a multiplicity of 2.
has a multiplicity of 3.
has a multiplicity of m, where m is a positive integer.
We were given the root .
If
Then the multiplicity of the root is 1.
If
Then the multiplicity of the root is 4.
Since the polynomial function or equation is not given in the question, we cannot determine the multiplicity of this root.
But I hope with this explanation, you can refer to the original(complete) question and choose the correct answer.
