Question
A fuel mixture of 40% Ethyl Alcohol gas and 60% n-Butane gas, on a moles basic, at 25 degree C and 100 kPa is combusted with 400% theoretical air at 430 degree C and 100 kPa. For this steady-state process, the products of combination exit the combustion chamber at 1500 degree C and 100 kPa. (a) Write the theoretical (or stoichiometric) chemical reaction. (b) Write the actual chemical reaction. (c) Determine the mole fraction of the actual products of combination, and (d) Compute the heat transfer per kmole of fuel.Explanation / Answer
due to negative charged sphere,
E1 = k q / r^2 = (9 x 10^9) (1.90 x 10^-6) / (0.550 / 2)
= 62181.8 N/C towards the negative charged sphere
due to positively charged sphere,
E2 = (9 x 10^9) (3.35 x 10^-6) / (0.55 / 2)
= 109636.4 N/C towards the negatively charged
(A) magnitude of E = E1 + E2 = 171818.2 N/C Or 1.72 x 10^5 N/C
(B) towrads the negatively charged sphere
