Question:
1 kmol of gaseous methane (CH 4) is mixed with the correct amount of air in a closed vessel. The pressure and temperature of the mixture are 1 bar and 298 K respectively. The mixture is ignited. Estimate the adiabatic temperature of combustion.
Answer: ~2743 K
OK, so first I...
A sphere, 14.7 mm in diameter, drops at a rate of 0.08 m/s in oil
µ = 0.1 Ns/m^2 , σ = 0.85 ). Calculate the drag force acting on the sphere.
[Answer: 1.85e-3 N]
F_d=0.5*rho*C_d*A*u^2, Re=u*p*L/μ
I attempted to find the Re, but am struggling on finding the coefficient of drag...
