Carbon tetrachloride $(\mathrm{SG}=1.6)$ is pumped at a rate of $2 \mathrm{gpm}$ through a pipe that is inclined upward at an angle of $30^{\circ}$. An inclined tube manometer (with a $10^{\circ}$ angle of inclination) using mercury as the manometer fluid $(\mathrm{SG}=13.6)$ is connected between two taps on the pipe that are $2 \mathrm{ft}$ apart. The manometer reading is $6 \mathrm{in}$. If no heat is lost through the tube wall, what is the temperature rise of the $\mathrm{CCl}_{4}$ over a $100 \mathrm{ft}$ length of the tube?
