Problem 141P
An oil pipeline and a 1.3–m3 rigid air tank are connected to each other by a manometer, as shown in Fig. P3–149. If the tank contains 15 kg of air at 80°C. determine (a) the absolute pressure in the pipeline and (b) the change in Δh when the temperature in the tank drops to 20°C. Assume the pressure in the oil pipeline to remain constant, and the air volume in the manometer to be negligible relative to the volume of the tank.
Solution to 141P
Step 1 of 5
In this question we need to determine the absolute pressure existing in the pipeline and the change in differential height when the temperature in tank drops to . We have to assume that the pressure in oil pipeline is constant and the volume of air present in air in the manometer is very less compared to volume of air in tank.
Given data:
Volume of air tank
Mass of air in air tank
Temperature of air tank,
