Question
Chapter 9, Problem 9.31P
Interpretation Introduction
Interpretation:
The method by whichmachines make snow in ski resorts needs to be explained.
Concept introduction:
Ski resorts are popular for winter sports such as snowboarding and skilling etc. where the snow required for the sports are made from snow cannon.
Snowmaking is defined as the process used for snow by driving water and air under pressure through a snow gun or snow cannon. Snowmaking is largely used at ski resorts to increase natural snow. This provides ski resorts to improve the safety of their snow cover and to increase their ski seasons from late fall to early spring.

An ideal gas with MW of 29 g/mol, cp = 1.044 kJ/kgK and c₁ = 0.745
kJ/kgK contained in a cylinder-piston assembly initially has a pressure of
175 kPa, a temperature of 22°C, and a volume of 0.30 m³. It is heated
slowly at constant volume (process 1-2) until the pressure is doubled. It
is then expanded slowly at constant pressure (process 2-3) until the volume is doubled. Draw a figure
of the system and the PV diagram showing each state and the path each process takes. Determine
the total work done by the system and total heat added (J) in the combined process.

A communication satellite is in stationary (synchronous) orbit about the earch (assume
altitude of 22.300 statute miles). Its transmitter generates 8.00 W. Assume the transmit-
ting antenna is isotropic. Its signal is received by the 210-ft diameter tracking parabo-
loidal antenna on the earth at the NASA tracking station at Goldstone, California. Also
assume no resistive loss in either antenna, perfect polarization match, and perfect
impedance match at both antennas. At a frequency of 2 GHz, determine the:
(a) power density (in watts/m²) incident on the receiving antenna.
(b) power received by the ground-based antenna whose gain is 60 dB.
