A control value, with a turndown ratio of 50, follows equal percentage characteristics. The flow rate of a liquid through the value at 40% stem positions is 1 m$^{3}$/h. What will be the flow rate in m$^{3}$/h at 50% stem positions, if the pressure drop across the value remains unchanged? (Up to 2 digits after the decimal point.) $\_\_\_\_\_\_\_$
