4. Underwater sonar-based monitoring of the seas often involves sending ping-like signals from the sea surface to a receiving, and listening for the reflected signal s]. The sound speed underwater is a function of the static pressure P in [Pa], salinity of the water S in [parts per thousand], latitude Ψ of the location in [deg], temperature T in [deg C], and depth z in [km]. The static pressure is P-99.5(1-0.00263cos 2y)Z+0.239 where...

The thermodynamic state of a soap film can be described by state variables (T, S) and (σ, A), where σ and A are the surface tension and surface area of the soap film, respectively. When stretching the film, the work done on the system is equal to σdA. The surface tension of the film is found to be a function of temperature only. Around room temperature, it can be expressed as σ(T)=σ0−λT, where σ0 and λ are positive constants. 1)...

1. In the figure below, a solution containing lung extract
exhibits hysteresis in is surface tension versus area relationship.
This means the surface tension is higher during inflation of the
lung than deflation.

"Vapor Pressure of Water" assignment:
VAPOR PRESSURE OF WATER INTRODUCTION All liquids exist in equilibrium with the vapor state. As temperature increases, this equilibrium shifts more and more in favor of the vapor until one reaches the boiling point, at which all liquid is converted to gas. The pressure exerted by the vapor over the liquid is known as its vapor pressure and is a function of temperature. Boiling occurs at the temperature at which the vapor pressure is equal...

2.3 Analytic form of transfer function. In certain cases the transfer function is available as an analytic expression. One common transfer function used for resistance temperature sensors (to be discussed in Chapter 3) is the Callendar- Van Duzen equation. It gives the resistance of the sensor at a temperature T as R(T)= Ro(1+AT+ BT2 - 100CT3 +CT*) [2), where the constants A, B, and C are determined by direct measurement of resis tance for the specific material used in the...
