A strain gauge pressure sensor has the following specification. Will it be suitable for the measurement of pressure of the order of 100 kPa to an accuracy of +_5 kPa in an environment where the temperature is reasonably constant at about 20°C?
Specification:
Ranges: 2 to 70 MPa, 70 kPa to 1 MPa
Excitation: 10 V d. c. or a. c. (r. m.s.)
Full range output: 40 mV
Non-linearity and hysteresis errors: +_0.5%
Temperature range: - 54 to +120°C

A2-m rigid tank initially contains saturated water vapor at 100 kpa. the tank is connected to a supply line through a valve. steam is flowing in the supply line at 600 kpa and 300 c. the valve is opened, and steam is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. a thermometer placed in the tank indicates that the temperature at the final state is 200°c. determine (a) the mass of steam that has entered the tank (b) the amount of heat transfer.
