Answer:
Spark
Explanation
The spark plug fires igniting the fuel. In diesel trucks the air is compressed until ignition.
Standard curves are used to determine the concentration of substances. They are obtained by relating a measured quantity to the concentration of the substance of interest in "known" samples, i.e. Standards of known concentration. These standards provide a reference to determine unknown concentrations.
Answer:
The inertial or convection term is dominant in the laminar regime. Generally, the laminar flow occur when the fluid is viscous and when it is moving very slowly.
Laminar regime is characterized by the low momentum convection and the high momentum diffusion.
The laminar regime flow is basically occur at the low velocities. When the reynolds number is less than 1, then the fluid exhibited stokes. Then, the viscous force in the fluid deaminate the convection or inertial forces.
Answer:
Explanation:
Coefficient of performance (COP) of refrigeration cycle is given by:
We are given:
COP= 5
We can also write Coefficient of performance (COP) of refrigeration cycle as:
Amount of heat absorbed by low temperature reservoir can be found as:
According to first law of thermodynamics amount of heat rejected by hot reservoir is given by:
We are given the mass of 0.96 kg. So,
Since it is a saturated liquid-vapour mixture 
.
From Refrigerant 134-a tables 
at 
is 61.3 C. (We calculated this by interpolation)
Converting from Celsius to Kelvin:
We are given:
Converting 
from Kelvin to Celsius:
From Refrigerant 134-a tables 
at 
is 356.9 KPa. (We calculated this by interpolation).
