    Fluid Mechanics: Pressure Calculation for a Horizontal Bend in a Pipeline

    Homework Statement A horizontal bend in a pipeline conveys water at a discharge at 1000l/s gradually reduces from 600mm to 300mm and deflects the flow through an angle of 60 degrees. At the larger end the pressure is 170000N/m^2. Determine the magnitude and direction of the force exerted on...

    How Do You Calculate Sound Intensity from a Decibel Level?

    this is how i got my answer. 45= 10[logI - Log10^-12] 4.5= LogI +12 -7.5 = log I BECAUSE THE BAS WAS 10 SO 10^-7.5 = 3.1622 X 10^-8

    How Do You Calculate Sound Intensity from a Decibel Level?

    Homework Statement A sound-level meter placed 150 mm from a small sound source records a reading of 45dB. What is the intensity at that point. Homework Equations I m using this equation IL = 10 log(I/I.) where I. is the lowest intensity i think which should be 10^-12 W/m^2. The...
