A cylindrical pressure vessel made of steel has diameter of $3$ m and wall thickness of $15$ mm. For steel, Young's modulus and Poisson's ratio are $210$ GPa and $0.3$, respectively. The cylinder is designed such that the allowable normal strain at the outer cylindrical surface is equal to $0.00034$. The permissible pressure in the tank is $\_\_\_\_$ kPa (rounded off to $1$ decimal place).
