You have the system reversed. The transformer would come first and then the rectifier, since the transformer can’t work on DC. With a turns ratio of 8:1 the voltage on the secondary would be 240/8 = 30 volts.
The peak voltage of a sine wave is the RMS (root mean squared voltage) x square root of 2. That would be 42.5 volts. A typical silicon diode drops about 0.7 volts so the peak voltage would be about 42 volts.
