A nova is a sudden drastic change in the luminous intensity of a star. The change in intensity is due to the explosion of the outer surface of the star, resulting in extreme temperatures and radiation throughout the space.. Nova occurs when a white dwarf engulfes mass on its surface from a binary companion red giant. This process gets continued till there is a breakdown of the mass that the white dwarf can carry on its surface. Many such nova systems have been found, yet this field is still a developing field in astronomy. In the year 1984, on July 28, PW Vul was discovered, it was later found to have a periodicity of about 15 days and thus a recurrent nova. The Parametrization of a nova is a crucial and important process, to state the process of before and after the nova situation. Not much study is done on PW Vul. In this paper, the ejected mass right after its detection is calculated by following the Uniform disk model. For this, the brightness temperature of the nova is calculated to be 6.1106K, which is a strong suggestion of non-thermal synchrotron radiation from the nova. The ejected mass is calculated to be 1.1210-5M, which is under the expected range as suggested by of 10-7M -10-4M, by Steven N. Shore
