Solution

Let's break down the equation you provided and solve it step by step:

The equation is:

((0.032)50.2×Le)1/2=((0.06)50.2×600)1/2+((0.029)50.02×600)1/2\left(\frac{(0.032)^5}{0.2 \times L_e}\right)^{1/2} = \left(\frac{(0.06)^5}{0.2 \times 600}\right)^{1/2} + \left(\frac{(0.029)^5}{0.02 \times 600}\right)^{1/2}

Step 1: Simplify the right-hand side

Start by simplifying the two terms on the right-hand side separately.

  • For the first term: (0.06)50.2×600\frac{(0.06)^5}{0.2 \times 600} First, calculate 0.0650.06^5: 0.065=0.000077760.06^5 = 0.00007776 Now calculate 0.2×600=1200.2 \times 600 = 120. Thus, the first term becomes: 0.00007776120=0.000000648\frac{0.00007776}{120} = 0.000000648 Now, take the square root: 0.0000006480.000804\sqrt{0.000000648} \approx 0.000804

  • For the second term: (0.029)50.02×600\frac{(0.029)^5}{0.02 \times 600} First, calculate 0.02950.029^5: 0.0295=0.0000002053790.029^5 = 0.000000205379 Now calculate 0.02×600=120.02 \times 600 = 12. Thus, the second term becomes: 0.00000020537912=0.000000017113\frac{0.000000205379}{12} = 0.000000017113 Now, take the square root: 0.0000000171130.000131\sqrt{0.000000017113} \approx 0.000131

Step 2: Add the two terms on the right-hand side

Now add the results from the two terms: 0.000804+0.000131=0.0009350.000804 + 0.000131 = 0.000935

Step 3: Simplify the left-hand side

Now, let's simplify the left-hand side of the equation: ((0.032)50.2×Le)1/2\left(\frac{(0.032)^5}{0.2 \times L_e}\right)^{1/2} First, calculate 0.03250.032^5: 0.0325=0.0000010485760.032^5 = 0.000001048576 So the expression becomes: (0.0000010485760.2×Le)1/2\left(\frac{0.000001048576}{0.2 \times L_e}\right)^{1/2} We know that this equals 0.0009350.000935, so: (0.0000010485760.2×Le)1/2=0.000935\left(\frac{0.000001048576}{0.2 \times L_e}\right)^{1/2} = 0.000935

Step 4: Square both sides to eliminate the square root

Now, square both sides to eliminate the square root: 0.0000010485760.2×Le=(0.000935)2\frac{0.000001048576}{0.2 \times L_e} = (0.000935)^2 Calculate the square of 0.0009350.000935: (0.000935)2=0.000000873225(0.000935)^2 = 0.000000873225 Thus, the equation becomes: 0.0000010485760.2×Le=0.000000873225\frac{0.000001048576}{0.2 \times L_e} = 0.000000873225

Step 5: Solve for LeL_e

Now, solve for LeL_e: 0.000001048576=0.000000873225×0.2×Le0.000001048576 = 0.000000873225 \times 0.2 \times L_e 0.000001048576=0.000000174645×Le0.000001048576 = 0.000000174645 \times L_e Now, divide both sides by 0.0000001746450.000000174645: Le=0.0000010485760.000000174645L_e = \frac{0.000001048576}{0.000000174645} Le6.0L_e \approx 6.0

Final Answer:

Le6L_e \approx 6
