Calculate maximum temperature reached and change in internal energy, heat transfer during process?
Vol is 0.2m^3 of mixture of fuel and air at 1.2 bar and 60°c compressed until it's pressure becomes 12bars with Temp of 270°c. It's then ignited suddenly at constant volume and it's pressure becomes twice the pressure at the end of compression.( Cp=1.072kj/kg and R=294j/kgk.

To calculate the maximum temperature reached and the change in internal energy and heat transfer during a process, we need to know the initial and final states of the system, as well as any relevant properties such as specific heat capacities and the amount of material involved.
The change in internal energy (ΔU) can be calculated using the formula:
ΔU = Q - W
where Q is the heat transfer into the system and W is the work done by the system. If the process is adiabatic (no heat transfer), then ΔU = -W.
The heat transfer (Q) can be calculated using the formula:
Q = m * c * ΔT
where m is the mass of the material, c is the specific heat capacity, and ΔT is the change in temperature.
To calculate the maximum temperature reached, we need to consider the specific heat capacity of the material and the amount of heat transferred into the system. The maximum temperature will occur when all the heat transferred is used to increase the temperature of the material.
Once we have the maximum temperature reached and the change in internal energy, we can calculate the heat transfer during the process using the formulas above.
It is important to note that these calculations are based on idealized assumptions and may not accurately represent real-world processes. Additional factors such as heat losses to the surroundings, changes in phase, and other complexities may need to be considered in more detailed analyses.
