In summary, the formula ºC.min-1 is used to calculate the rate of temperature change during one minute. However, the rate of change may not be constant and can vary depending on the temperature. It is important to consider the specific point in time for accurate calculations.
The question: The gauge pressure in your car tires is $2.60 * 10^5 N/m^2$ at a temperature of $35.0°C$ when you drive it onto a ferryboat to Alaska. What is the gauge pressure later, when the temperature has dropped to −28°C? Assume that the volume has not changed. Answer needed in atm.
To calculate the pressure at the outlet of a pump we use pump performance characteristics i.e. charts giving pump head as a function of volumetric flow. When the fluid flows through a pump, it's temperature slightly rises. Is there a formula or other method to calculate the temperature rise in a pump?
Along with this, you subtract the initial density with the change in density due to the temperature difference. When the fluid undergoes a temperature change, the coefficient of volumetric expansion will fall into place as the temperature provides kinetic energy and with enough of this energy, the liquid can expand.
At room temperature, the bulk modulus of water is 2150 MPa, so a 1% compression would cause a pressure of 21.5 MPa. $\endgroup$ – Chet Miller Commented Oct 17, 2017 at 13:17
where $\Delta l$ is the length change of the element. That really just stems from the definition of Young's Modulus. From here, it's easy to see where the equation for thermal stress comes from -- the linear coefficient of thermal expansion multiplied by the change in temperature gives the change in length of the element.
To calculate temperature change over time, you will need to know the initial temperature and the final temperature. Then, you can use the formula: temperature change = final temperature - initial temperature. This will give you the change in temperature over the specific time period. What units should I use to measure temperature change? The ...
The formula has $2$ variables, because heat is not a constant. Heat is a flow of energy, and we must understand the change of entropy as a result of that flow. Normally the temperature increases when there is an heat input in a mass of material, So, energy and temperature are related. But they don't tell the whole history.
The barometric formula is the same as the hypsometric formula if you set T=15. The reason for T+273.15 is just to put the temperature in Kelvin. This formula works to an altitude of about 9000m where the change in pressure with altitude becomes less linear. Source: BMP180 Datasheet
