A U-tube manometer employs a special oil having a specific gravity of 0.2 for the manometer fluid. One side of the manometer is open to local atmospheric pressure of 24.3 inHg and the difference in column heights is measured as 10 cm±1.0 mm when exposed to an air source at 35◦C. Standard acceleration of gravity is present. Calculate the pressure of the air source in pascals and its uncertainty.

1. (a)Plot the Voltage vs. Displacement graph of LVDT Transducer by moving the core in steps of 0.1mm in both Left and Right directions. (b)Calculate the Sensitivity of LVDT Transducer from the above graph. (c) What is the relationship between input voltage and output voltage of Transformer, given N1, N2 are number of turns in the primary and secondary coils respectively?
