At a soft drink bottling plant, a horizontal section of pipe carrying citric acid in liquid form goes from a cross-sectional area of 8.00 cm2, fluid flow speed of 210 cm/s, and pressure of 1.40 x 10^5 Pa to a section of pipe with a cross-sectional area of 4.00 cm2. The density of the citric acid is 1660 kg/m3. For the section of smaller pipe, determine the liquid flow speed and the liquid pressure. (a) the liquid flow speed (b)...

You are tasked with determining the uncertainty in the mass flow rate of a liquid flowing through a pipe. You are able to measure the density of the fluid by collecting 1L of the fluid in a graduated cylinder with markings every 10mL, and weighing the fluid on a scale with uncertainty of ± 1 g by excluding the weight of the cylinder itself (density = mass/volume). You find the weight of the fluid to be 789g. You measure the...

L 2. Steady statemass balance: Water is flowing at steady state in a 0.1 meter-diameter pipe with a maximum velocity (turbulent profile) of 0.3 meters/sec. The pipe then goes through an expansion, to where it is then flowing in a 0.5 meter-diameter pipe, and the flow regime has changed from turbulent to laminar. In the second section of pipe, calculate the velocity as (a) block flow profile (Vavg), and (b) maximum velocity in laminar flow profile? HINT: you will need...
