Some modifications in your .delete click evetn will solve your problem like,

$('.delete').click(function () {
    // check for length of rows
    if($('.one').length==1){
        alert("This is default row and can't deleted");
        return false;
    }
    var parent = $(this).closest('.one');
    $(this).parents(".one").remove();
    calculate(parent);
    // reset serial numbers again
    $('.sno').each(function(i){
        this.value=i+1;
    })
});
