heat transfer

The water flows through a horizontal pipe with a diameter of 20 cm and a length of 3 m. The inlet temperature of the water to the pipe is 20°C and the outlet temperature is 70°C. The wall temperature is kept constant at Tw=90°C. Since the transfer coefficient in the pipe is h=60 W/m2K, calculate the amount of heat transferred to the water
