Answer: =
Explanation:
= P / (R * T) P- Pressure, R=287.058, T- temperature
From the given that
Sample mean(pressure) = 120300 Pa
Standard deviation (pressure) = 6600 Pa
Sample mean(temperature) = 340K
Standard deviation(temperature) = 8K
To calculate the Density;
Maximum pressure = Sample mean(pressure) + standard deviation (pressure) = 120300+6600 = 126900 Pa
Minimum pressure = Sample mean (pressure) - standard deviation (pressure)= 120300-6600 = 113700 Pa
Maximum temperature = Sample mean (temperature) + standard deviation (temperature) = 340+8 = 348K
Minimum temperature = Sample mean (temperature) - standerd deviation (temperature) = 340-8 = 332K
So now to calculate the density:
Maximum Density= Pressure (max)/(R*Temperature (min))= 126900/(287.058*332)= 1.331
Minimum density=Pressure(min)/(R*Temperature (max))= 113700/(287.058*348)= 1.138
Average density= (density (max)+ density (min))/2= (1.331+1.138)/2= 1.2345
cheers i hope this helps
Explanation:
<u>(a)</u>
<u>The measure of material's ability to conduct thermal energy (heat) is known as thermal conductivity.</u> For examples, metals have high thermal conductivity, it means that they are very efficient at conducting heat.<u> The SI unit of heat capacity is W/m.K.</u>
The expression for thermal conductivity is:
Where,
q is the heat flux
is the thermal conductivity
is the temperature gradient.
<u>(b)</u>
<u>Heat capacity for a substance is defined as the ratio of the amount of energy required to change the temperature of the substance and the magnitude of temperature change. The SI unit of heat capacity is J/K.</u>
The expression for Heat capacity is:
Where,
C is the Heat capacity
E is the energy absorbed/released
is the change in temperature
<u>(c)</u>
<u>Thermal diffusivity is defined as the thermal conductivity divided by specific heat capacity at constant pressure and its density. The Si unit of thermal diffusivity is m²/s.</u>
The expression for thermal diffusivity is:
Where,
is thermal diffusivity
is the thermal conductivity
is specific heat capacity at constant pressure
is density
Sensor/Detectors/Transducers are electrical, opto-electrical, or electronic devices composed of specialty electronics or otherwise sensitive materials, for determining if there is a presence of a particular entity or function. Many vehicles including cars, trains, buses etc. all use sensors to monitor oil temperature and pressure, throttle and steering systems and so many more aspects.
Answer:
Explained below
Explanation:
The isohyetal method is one used in estimating Rainfall whereby the mean precipitation across an area is gotten by drawing lines that have equal precipitation. This is done by the use of topographic and other data to yield reliable estimates.
Whereas, the arithmetic method is used to calculate true precipitation by the way of getting the arithmetic mean of all the points or arial measurements that will be considered in the analysis.
