Solve Equation 2.35
beta = ARCTAN[C1/(C2*C3 + C4)] = ARCTAN[1/(214.25*0.0423 + 0.002)] = 0.1099 radians
Calculate Algebraic Constants for Equation 2.38
C1 = M/N + SIN(lambda + beta) = 2.428 + SIN(0.002 + 0.1099) = 2.5397
C2 = M/N + 1 = 2.428 + 1 = 3.428
Solve Equation 2.38
eta' = eta(C1/C2) = 0.016(2.5397/3.428) = 0.012
Calculate Algebraic Constants for Equation 2.34
C1 = (L2/L1)COS(theta) _ (0.971/0.25)COS(0.1651) = 3.8312
C2 = SIN(theta)COS(beta) = SIN(0.1651)COS(0.1099) = 0.1634
C3 = (L2/L1)eta' _ (0.971/0.25)0.012 = 0.0466
C4 = (L3/L1)(Fd'/VVS) _(0.410.25)(0.96/58.3) = 0.0263
CS = SIN(lambda + beta) = SIN(0.002 + 0.1099) = 0.1117
C6 = (L4/L1)(FI'/VVS) _(0.971/0.25)(0.96/58.3) = 0.064
Solve Equation 2.34
SF = C1/[C2 + C3 + (C4)(CS) + C6] = 3.8312/[0.1634 + 0.0466 +(0.0263)(0.1117) + 0.064] = 13.83
