Chapter 3 Pressure Measurement Examples Example 3.3 A special high pressure U tube manometer is constructed to measure pressure differential in air at 13.8 MPa and 20oC. When an oil having a specific gravity of 0.83 is used as the fluid‚ calculate the differential pressure in N/m2 that would be indicated by a 135 mm reading. p − pa = m g h( gc m − f ) = (0.83)(1000) = 830kg/m 3 = = p 13.8 × 10 6 = f a RT (287)(293) g h( m − f ) p − pa = gc = 9.81(0.135)(830 − 164.11) = 881.51N/m 2 Example

definitely use a multitester for safety reasons. Multitesters can be used with the current off or on in most cases‚ although using the device with the current on can sometimes result in damage to the device. Theory Ammeters are employed for measuring current in a circuit and connected in series with the circuit. As ammeter is connected in series‚ the voltage drop across ammeter terminals should be as low as possible. This requires that the resistance of the ammeter should be as low as possible

Answer to Questions 1. Describe the type of meter movement used in the analog meters. The two analog meters—namely‚ the voltmeter and the ammeter—employ the d’ Arsonval meter movement. The movement consists essentially of a movable iron-core coil mounted on a pivot between the poles of a permanent magnet. When current flows through the coil‚ it creates a torque which causes the pointer to deflect. The amount of current through the coil determines the deflection of the pointer‚ which is registered

battery is bad. If you measure the battery to be less volts than the rated volts of the battery the condition of the battery will always be bad. Learning how to read all these meters can be useful in future labs because now I have the knowledge of measuring volt and ampere meters and I can always find the readings of any meter. Also there is importance of understanding the scales in the outside world because bathroom scales‚ speedometers‚ even rulers all have major divisions so you can utilize this

Case #2: The Craddock Cup 3/21/13 In order to decide whether or not to keep the Craddock Cup‚ we needed to classify the expenses as either fixed and sunk or variable‚ fixed and sunk costs are not relevant so they are not included in the revised statement. Exhibit A shows an income statement that is revised in this manner (under the revised column). The first expense we found not relevant is the city field rental. We found that this expense is fixed‚ where $1‚200 is allocated to this weekend‚ a

Text: Measuring economic activity There are a large number of statistics produced regularly on the operation of the world’s major economies. The UK’s economy is no exception in this respect. You will probably have noticed that often the headlines in newspapers or important items on television news programmes relate to economic data and the implications for individuals and businesses. A prime example of this occurs when interest rates are increased: the media responds by highlighting the adverse
