Pluto has no atmosphere and has an average orbital diameter that is 39.2 times that of the earth. The mean surface temperature is 37 K. Estimate the albedo of Pluto.
Determine the albedo value of Pluto.
Answer to Problem 1P
The albedo value of Pluto is
Explanation of Solution
Given information:
The average orbital diameter of Pluto is 39.2 times of the earth.
Mean surface temperature
Pluto has no atmosphere.
Calculation:
The solar flux at the outside of the earth’s atmosphere
Find the Insolation of Pluto
Let the albedo is a.
The value of Stefan Boltzmann constant is
The expression to find the temperature (T) is given below:
Therefore, the albedo value of Pluto is

A major transmission pathway of the novel coronavirus disease 2019 (COVID- 19) is through droplets and aerosols produced by violent respiratory events such as sneezes and coughs (Fig. 1). For the purpose of providing public health guidelines, we would like to estimate the amount of time it takes for these droplets to settle from air to the ground. The relevant parameters are the settling time (ts), the initial height of the droplets (H), gravitational acceleration (g), density of the droplets (pa), radius of the droplets (R), as well as dynamic viscosity of the ambient air (Pair). Use dimensional analysis and the Buckingham theorem to answer the following questions: 1. Find the independent dimensionless parameters using the table method. Then, express the settling time as a function of the other relevant parameters. Your solution should match the physical intuition that the settling time scales linearly with the initial height. 2. How would the settling change if the…arrow_forward
