Increasing Pipe size after a smaller pipe?

[Truelight]

Ok so i am installing a drip irrigation to a large (half acre) berry patch. The pipe size from the well is 1" before and after the pressure tank. I will be putting an inline injector pump that has 3/4" fittings right after the pressure tank. I plan on increasing to 1 1/2" to get to the berry patch. So I will be going from 1" to 3/4" to 1 1/2". What is that doing to my pressure and volume? Is increasing pipe size after a smaller pipe beneficial? Thank you

You’ll have less friction loss, you won’t get anymore volume than the 3/4 will allow......
