Final answer:
The temperature of the exhaust in an exhaust pipe can be approximated using the equation Q = mcΔT, where Q is the heat transfer, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature.
Step-by-step explanation:
The temperature of the exhaust in an exhaust pipe can be approximated using Equation 4.8, which assumes the process is slow and reversible. The equation uses the change in temperature (ΔT), the heat transfer (Q), and the mass of the substance (m). The increase in temperature can be calculated using the equation Q = mcΔT, where m is the mass of the substance and c is the specific heat capacity.
For example, let's assume we have mineral oil in a one-meter section of pipe. The mass of the mineral oil will be given, and we can use the specific heat capacity of the mineral oil to calculate the increase in temperature.
