pressure drop in a pipe due to surface roughness. This is to be done using a range of flow rates that are laminar‚ turbulent and in the critical zone. Theory The Reynolds number represents the ratio of inertial forces to viscous forces within a fluid flow. This number is calculated using the diameter (D measured in metres) as the length parameter‚ with the viscosity of the liquid (µ in kgm.s)‚ the density (ρ in kgm3) and the flow rate (U in ms): Re = ρUDμ If the Reynolds number is less than

port A at a rate of W kg/s. The steam transfers heat to a fluid at the tube side .The steam condenses during this process and leaves the shell side at the port B at a temperature Ts. The tube side fluid enters the heat exchanger at C with a flow rate of M kg/s at a temperature Ti and leaves at D at a temperature To. The heat loss QH from the steam can be expressed as QH = W(λ + CpH.(Tv-Ts)) Similarly‚ the heat gained by the tube side fluid QC can be expressed as QC= M.CpT. (Ti-To) The heat transfer

ABSTRACT Firstly‚ the objectives of the experiment are to observe the characteristics of the flow and to compute the Reynold’s number. Using the Solteq Osbourne Reynold’s Demonstration (model FM 11) in this experiment‚ with different of water volume flowrate‚ the characteristics of the flow could be determined. The rock inside the stilling tank are to calm the inflow water so that there will not be any turbulence interfere with the experiment. The water inlet and outlet valve and dye injector utilized

SUMMARY This experiment has four objectives to it of which are measuring the standard performance characteristics of the pump‚ comparing the performance characteristics for three different Reynolds numbers and explaining the effects observed and to also make predictions about the performance for a pump with an impeller diameter of 228mm using the data obtained in the experiments. This experiment was conducted under room temperature. The motor was first adjusted to 3000 rpm and the input valve which

increases velocity and decrease pressure while an Orifice plate is a device which measures the rate of fluid flow. The Venturi Tube and Orifice Plate are basically used to determine flow rate in piping systems. Both of them used the same principle which is Bernoulli’s Equation. Based on Bernoulli’s Equation which says that there is a relationship between the pressure of the fluid and velocity of the fluid. In a flow metering device‚ the downstream pressure before an obstruction will be higher than the
