\[ x^{2} \frac{d^{2} y}{d x^{2}}-x \frac{d y}{d x}-3 y=x^{2} \log x \] \[ \frac{d^{4} y}{d x^{4}}-y=\cos x \cosh x \] lve: \( \left(D^{4}+2 D^{2}+1\right) y=x^{2} \cos x \)2 answers -
With the help of the calibration curve of the hole plate and knowing the diameter of the pipe, please proceed to calculate: Speed, Re, f and hf. We know: onom=1in hl=14.375 in H20, Q=310GPH, Q=0.
Con ayuda de la curva de calibración de la placa orificio y conociendo el diámetro de la tubería, por favor proceda a calcular: Velocidad, Re, fy hf. (35pts) conocemos: \( \emptyset \) nom \( =1 \)2 answers -
