Name: ______________________________________________ Date of lab: ______________________ Section number: M E 345._______ Lab 12 Precalculations – Individual Portion Fluid Measurement Lab: Pressure, Velocity, and Fluid Measurements Precalculations Score (for instructor or TA use only): _____ / 20 1. At a temperature of 22 o C and a pressure of 98.5 kPa, calculate the air density using the ideal gas law. If the mass flow rate of the air is 0.025 kg/s, calculate the volume flow rate of the air in m 3 /s. Show all your work in the space below. 2. Repeat for an air temperature of 50 o C. 3. A Pitot-static probe is used to measure air velocity at a temperature of 22 o C and a pressure of 98.5 kPa. The pressure difference is 1.00 inches of water column. (Use ρ water = 1000 kg/m 3 and g = 9.807 m/s 2 .) Calculate the air speed in m/s. Show all your work in the space below. 4. Repeat for an air temperature of 50 o C.

Fluid Measurement Lab: Pressure, Velocity, and Fluid Measurements Author: John M. Cimbala, Penn State University Latest revision: 29 April 2008 Introduction and Background ( Note : To save paper, you do not need to print this section for your lab report.) Many kinds of instruments have been designed to measure pressure and velocity in flowing fluids. In this lab, you get hands-on experience using some of these instruments. In addition, you measure the decay of centerline temperature and axial velocity along the axis of a jet. This lab has eight stations. At the time of the lab, you will be told which of these you will run (probably 7 out of the 8, depending on the condition of the equipment): Pressure calibration station : Calibration and comparison of an analog and a digital pressure meter Yaw sensitivity station : Comparison of the performance of a Kiel probe and a Pitot probe when misaligned. Thermoanemometer station
