Examples of Applications

Abstract

This chapter presents 13 exercises solved on the topics of Chaps. 1–6, aiming at consolidating the physical principles to solve applied problems. Exercises 1 and 2 provide the calculation of the energy of one mole of photons and the modeling of continuous solar radiation in the eventual absence of measured data. Exercise 3 shows the calculation of transmissivity using the radiation equation. Exercises 4 and 5 estimate the daily radiation flows in locations with measured data, also considering the emissivity and reflectivity of the surface. Exercise 6 calculates the sensitive heat flow on very small scales based on the wind profile and heat transfer. Exercises 7, 8, and 9 estimate heat and water vapor flows using the aerodynamic, eddy, and Bowen covariance methodologies, considering speed, atmospheric stability, soil heat flows, and turbulent fluctuations. Exercise 10 offers a complete assessment of the radiative thermal load in a building. Exercise 11 parameterizes the components of the turbulent kinetic energy balance. Exercise 12 shows the calculation of the particle sedimentation speed, following the principles of mass transfer in Stokes and inertial domains. Finally, Exercise 13 offers an application of the Bernoulli and mass conservation principles for estimating air velocity and pressure variation in open plains followed by downward restrictive valleys.
