Answer» RIGHT choice is (c) th=\(\FRAC{H}{12.56K(T_c-T_e)}\) × 10^3 Explanation: th is the THICKNESS of the piston HEAD, H is the Heat CONDUCTED, K is thermal conductivity factor, Tc-Te is the temperature from the center to edge of the piston. When all these are summed, we get th=\(\frac{H}{12.56K(T_c-T_e)}\times 10^3\). |
