2×∆𝑝=〖(𝑘〗_𝑓+0.033 𝐿/𝑑)×𝜌_𝑚×〖(𝑄/((𝜋×𝑑^2)/4))〗^2    d=?

To solve for \( d \) in the equation:

\[
2 \times \Delta p = \left(k_f + 0.033 \frac{L}{d}\right) \times \rho_m \times \left(\frac{Q}{\left(\frac{\pi \times d^2}{4}\right)}\right)^2
\]

we follow these steps:

### 1. Simplify the equation
Start by simplifying the expression inside the parentheses on the right-hand side.

The flow rate term can be rewritten as:

\[
\frac{Q}{\left(\frac{\pi \times d^2}{4}\right)} = \frac{4Q}{\pi \times d^2}
\]

### 2. Substitute this into the equation
Substitute the simplified term into the equation:

\[
2 \times \Delta p = \left(k_f + 0.033 \frac{L}{d}\right) \times \rho_m \times \left(\frac{4Q}{\pi \times d^2}\right)^2
\]

### 3. Expand the squared term
Expand the squared term:

\[
\left(\frac{4Q}{\pi \times d^2}\right)^2 = \frac{16Q^2}{\pi^2 \times d^4}
\]

Substitute this back into the equation:

\[
2 \times \Delta p = \left(k_f + 0.033 \frac{L}{d}\right) \times \rho_m \times \frac{16Q^2}{\pi^2 \times d^4}
\]

### 4. Solve for \( d^4 \)
Now, isolate the \( d^4 \) term:

\[
2 \times \Delta p = \frac{16Q^2 \times \rho_m \times \left(k_f + 0.033 \frac{L}{d}\right)}{\pi^2 \times d^4}
\]

Multiply both sides by \( d^4 \):

\[
2 \times \Delta p \times d^4 = \frac{16Q^2 \times \rho_m \times \left(k_f + 0.033 \frac{L}{d}\right)}{\pi^2}
\]

### 5. Rearrange to solve for \( d \)
Rearrange the equation to isolate \( d \):

\[
d^4 = \frac{16Q^2 \times \rho_m \times \left(k_f + 0.033 \frac{L}{d}\right)}{2 \times \Delta p \times \pi^2}
\]

At this point, solving for \( d \) involves more complex algebraic manipulation, potentially involving numerical methods if \( d \) appears on both sides. However, if simplifications or assumptions can be made (such as \( d \) appearing only on one side after further algebraic manipulation), you can solve for \( d \) more directly.

If additional specific values are given for \( \Delta p \), \( k_f \), \( \rho_m \), \( Q \), \( L \), or \( \pi \), these can be substituted in to further simplify or numerically solve for \( d \).

Would you like to proceed with a numerical example, or do you have specific values to use?
