A breakthrough by a Pennsylvania State University student has breathed new life into a century-old aerodynamic equation, ...

For example, the simultaneous equations \(3a + 2b = 17\) and \(4a - b = 30\) have no common coefficient as the coefficients of \(a\) are 3 and 4, and the coefficients of \(b\) are 2 and -1.

The conversion to flow coefficient C is given by the derived equation Where d = inside pipe diameter (or in this case ball valve diameter). This analytical method does not include the effects of ...

This confirms that the solution of 𝒙 = 1 is correct. When solving equations using brackets, the coefficient of \(x\) may be negative. The first step is to expand the brackets, taking care where ...
