The Antoine Equation can be used to estimate vapor pressure at various temperatures for different substances using sets of empirically-derived constants. The equation can be written as:   Where for water A = 8.07131, B = 1730.63, C = 233.426, T = temperature [°C], and P = vapor pressure [mmHg]. Note that with these constants the temperature and pressure must be provided in °C and mmHg, respectively. Using the Antoine Equation and the provided constants, what atmospheric pressure (provided in terms of % of standard atmospheric pressure) will permit water to boil at 75 °C?

A heat generating slab with thermal conductivity of k [W/m-K] and heat generation rate d" [W/m³] is perfectly insulated on the left side (x = 0) . h1 and is exposed to air with ambient temperature T1 [K] and convection coefficient of hi [W/m²-K] on the right as shown in Fig. 1. Neglect Air Slab radiation. Find out the temperature distribution (i.e., temperature as X= () a function of x) within the slab in terms of the variables shown in the Figure 1: Note the figure. indicated positive direction for reference.

To understand the heat transfer from a bar in cross flow, you conduct a series of experiments measuring the average heat transfer coefficient as a function of the free stream velocity. A schematic of the experiment and the accompanying results are shown below. L = 0.3 m h [W/m²-K] 60 40 V [m/s] 20 15 a) You expect the important dimensionless parameters to be related by a function of the form Nu = CRe Pr where C, m, and n are constants. The film temperature in both the experiments is approximately the same. Use the given experimental results to determine the constant m b) Calculate h for L = 0.75 m and V = 30 m/s.

==== 25°C and A closed rigid tank contains 0.5 kg of Refrigerant 22, initially at a temperature T₁ pressure p₁ = 6.0 bar. The tank is cooled until the temperature is T₂ = -10°C. Assume changes in kinetic and potential energy are negligible. Determine: a. final pressure [bar] Handwritten,no gpt b. heat transfer [kJ] during the process (indicate magnitude and direction)

Pressure drop AP depends on four variables: the diameter of the pipe D, the density of the fluid p, the kinematic viscosity of the fluid v and the mean velocity v. Applying Buckinham's Pi Theorem, a dimensionless pi-group can be identified using the following power product: [AP] = [D]ª[p]b[v][v]ª. Which of the following statements in term of [T] is correct? Select one: O [T]: -2 = -c-d [T]: -1 = -c-d [T]: -2 = -c-2*d [T]: -2 = -2*c-d [T]: -2=-c+d
