Pre sizing just fine, no need to adjust it, you've got TT, it's not an extraordinary strong hand, and on the other hand, you don't want to make it too cheap for V to call. So, a smaller or a larger isolation raise wouldn't be justified here. 3x+2x, standard, no need to overthink it.
Bet on the flop, though, is not necessarily good. Here's why: unless you have a lot of hands played against villain and you know exactly what he shoves with on that flop, you need to consider your overpair to beat his range in the long run. His range is wide here, and quite frankly, that should be none of your concerns in this very particular spot. I'd rather be wondering what range does he assign me there, given the 5x raise preflop. Of course he's likely to think that you've missed that flop, you've got AJ+ and KQ in your range here, and believe it or not, a fish loves to tell himself that you've got nothing, he hates telling himself that you have him. So, at least 2/3 bet on the flop.
Now, don't get me wrong, I'm not telling you that your opponent's range is not important, not at all. I'm telling you that in this particular spot, it's +ev to play against him, whether you'll end up winning or not. In the long run, it's gonna make you profit. Just like <sisyphusonroids> said, you only need 30% equity here.
