5. The model number for the Ametek PK ll Pneumatic Deadweight Tester in our lab is PK II-254WC-ss. Given this information, determine the range. minimum increment, and the number of each weight provided by Ametek.
6. How often does Ametek recommend that the deadweight tester be tested and (re) certified?
7. Table 1 of the results section of this lab has a column labeled "Ametek Uncorrected Pressure value, H20(Troom)". The values of pressure in this column have not been corrected for gravity, temperature and air head, Correction factor equations can be found on page 3 and 4 of the Ametek handbook.
Assuming that there is no air head, calculate the corrected tester output pressure for each generated pressure, and record in table 1, Ametek Corrected Pressure value, H20(T room) Note, the gravity constant for Bangkok Thailand is 9.7835 m/se. Assume that the room temperature is 25 C. Show one example calculation.
8. The corrected tester output pressures calculated in pre-lab Q#7 are referenced to water at 209e room temperature, but pressure reference to water at 4°C is required. Convert all of the corrected tester output pressures to pressure in units of inches of water at 4°C, and record in table 1, "Ametek Corrected Pressure Value, H204 The density of water at 49C is 999,97 kg/m and the density of water at 2025°C is 998.20 kg/m Show one example calculation
