An operator in a textile mill is operating six machines. If the sound pressure levels of each machine at his position are given in Table Q2(b): Determine the total sound pressure level (in decibels) and total mean square pressure (in N/m?) produced by all six machines at the operator position. (i) If the two machines, M1 and M2 are turned off, and assuming that total sound pressure level is 120 dB, analyze the sound pressure level of the background noise (in decibels) and its mean square pressure (in N/m²) at the operator position. (ii)

Derive an expression for the speed of sound based on van der Waals’ equation of state P = RT(v − b) − a/v2. Using this relation, determine the speed of sound in carbon dioxide at 80°C and 320 kPa, and compare your result to that obtained by assuming ideal-gas behavior. The van der Waals constants for carbon dioxide are a = 364.3 kPa·m6/kmol2 and b = 0.0427 m3/kmol.

Consider a U-tube whose arms are open to the atmosphere. Now equal volume of water and light oil (ρ=790 kg/m3) are poured from different arms. A person blows from the oil side of the U-tube until the contact surface of the two fluids moves to the bottom of the U-tube, and thus the liquid levels in the two arms are the same. If the fluid height in each arm is 102 cm, determine the gage pressure the person exerts on the oil by blowing.
