Calculate the cross-sectional area of the wire coil by measuring its radius and plugging this into the formula π*r squared. Step 4 Calculate the inductance using the following formula: Inductance = µ (N squared) A / length, where N is the number of turns in the coil, A is the cros...
Step 2: Calculate the cross-sectional areas A1 and A2.The cross-sectional area of the main part (section 1) and the neck part (section 2) can be calculated using the formula:A=πD24 For A1 (main part, diameter D1=86cm=0.86m):A1=π(0.86)24=π×0.73964≈0.580m2 For A2 (neck part...
Cross-sectional area - cross section - slice plane Now there is the question: How can we calculate the cross sectional area (slice plane) A from the wire diameter d and vice versa? Calculation of the cross section A (slice plane) from diameter d: r = radius of the wire d = diameter...

Next calculate the cross-sectional area of the bar. Measure the diameter of the bar and divide it by two to get the radius. Square this number and then multiply by pi. For example, if the diameter is two inches, divided by two to get a one inch radius, square it and get one inch...
measure the cross section and calculate the cross-sectional area. For example, a member with a rectangular cross-section of 1 x 2 inches has a cross-sectional area of 2 square inches. A member with a circular diameter of 2 inches has a cross-sectional area of (1 inch x 1 inch x pi...
What is the cross-sectional area of the nozzle if the speed of the water at the nozzle is 2.5 m/s? Step 1: Identify a spot in the pipe with a known area and calculate the area at that spot. The area is given and does not need to be calculated: A1=9.5 cm2. Step 2:...
The value obtained by dividing this repelling force by the cross-sectional area (the value converted to per unit area) is called “stress” (σ). With the external pulling force as P (N) and the cross-sectional area as a (m2), the stress is obtained as follows. σ = P / a — Fo...
