Record the readings of the three instruments at eight different speed settings of the tunnel: 15, 20, 25, 30, 35, 40, 45, & 50. 4. Plot two calibration curves with pressure transducer reading as the abscissa and micromanometer reading as the ordinate for the first, and micromanometer versus scannivalve as the second. Convert micromanometer data to read as total pressure in SI units [Pa]. 5.
Friction Objectives: To provide an understanding of the concept of friction. To calculate the coefficient of friction of an object by two methods. Materials: Ramp board: 3 - 4 feet long, 10 cm wide Can of soft drink or item of similar weight Friction block set-PK Protractor Scale-Spring-500-g Tape measure, 3-m Lab notes: Using the wooden block provided in LabPaq, a long board, a can of beans and the 500-g spring scale I will try and determine the force of kinetic friction, N, and the force of static friction, N while pulling the block at a constant speed. I will convert kg-mass to Newtons by multiplying the kg-weight by 9.8 m/s2, i.e., 100 g = 0.1 kg = 0.1 x 9.8 = .98 N.

In the late spring and early fall, strong offshore winds of sinking air typically develop, bringing heat and dryness to the area. In the spring, this is not usually a problem as vegetation is still moist from winter rains, but extreme dryness prevails by the fall. The warmest and driest months are typically June through September, with the highest temperatures occurring in September. Mid-summer (July-August) is often a bit cooler due to the sea breezes and fog which are normally most strongly developed then (Gildemeister, 2004, p. 109).

The experiment was divided into two parts using a different apparatus for each part. Part A: For this part of the experiment, the used apparatus was constructed by a pump type Dayton Split phase A.C. Motor 1/5 HP 1725 rpm 115 V sf 1.0 manufactured by Dayton Manufacturing Company, a tank, pipes (L drawn copper tubing type), valves, well type manometer, 1 venturi meter, 1 orifice meter and 4 pressures taps (figure 1). According to Daniel measurement, the theoretical accuracy of orifice meter is +/- 1% and the theoretical uncertainty of venturi meter is +/-1.0 %. Flow calibration is necessary for critical measurement and it results in +/- 0.25 % of uncertainty. The well type nanometer uncertainty is +/-1/2 of the smallest scale graduation.
