A double$-$fluid manometer is used$$ for measuring the pressure of an air pipe. If the fluid $1$ has a spesific gravity of $1\mathrm{.}15,$ determine the specific gravity of fluid $2$ where the air pressure in the pipe is $131$ kPa, height of the fluid $1$ is h$1=42$ cm and height of the fluis $2$ is h$2=14$ cm$.$ Take the atmaspheric pressure Patm $=100$ kPa. Write your answer with $2$ decimal figures. $($ g$=9\mathrm{.}81$ m$/$s$2,$ water $=1000$ kg$/$m$3)$
