A venturi meter is used to measure the flow speed of a fluid in a pipe. The meter is connected between two sections of the pipe (the figure); the cross-sectional area A of the entrance and exit of the meter matches the pipe's cross-sectional area. Between the entrance and exit, the fluid flows from the pipe with speed V and then through a narrow ''throat'' of cross-sectional area a with speed v. A manometer connects the wider portion of the...

(a) What is the fluid speed (in m/s) in a fire hose with a 8.50 cm diameter carrying 74.0 L of water per second? m/s (b) What is the flow rate in cubic meters per second? m3/s (c) Would your answers be different if salt water replaced the fresh water in the fire hose? Yes, because the velocity and the flow rate are directly proportional to the fluid's density. No, because the velocity and the flow rate are independent of...

An unknown fluid is forced to flow through a channel of length L, diameter D, and roughness E. You know the pressure and temperature changes from sensors at the inlet and outlet of the channel as well as the mass flow rate and heat transfer to the fluid. Find expressions for the specific heat capacity, density, thernal conductivity, and viscosity of this fluid. Assume steady state.

2. An understanding of fluid resistance in micro-channels is very important for designing a microfluidic system. Since the capillary tubes can have a variety of cross-sections, researchers have always been interested in understanding the resistance to water flow in micro-channels of various cross-sections. Fluid resistance R is defined as the ratio of pressure drop AP to the volumetric flow rate of medium Q along a specific length, say L of the channel. Evaluate the resistance to water flow in micro-channels...

2) (LON3) (30 points) Given that; Force =f(flow velocity, body length, fluid density, fluid viscosity, speed of sound) What is the minimum number of required experiments to express the force in terms of gven independent parameters. Find the dimensionless parameters in order to correlate the experimental data. (Assume that at least 10 points are required to fit a meaningful curve through experimental points of one independent parameter)
