1/2 inch will easily do that.
The size of the water pipe from the meter to the house should be determined based on the water flow rate needed for the house. It is recommended to consult with a professional plumber to determine the appropriate size of the water pipe for optimal water flow and pressure.
Hole or pipe size is not the only factor that determines flow of cubic feet per minute. The other factors are presssure and resistance.

No, water expands in size when frozen. That's why ice floats on water, and why pipe bursts occur when trapped water in them freezes.
Fixture unit demands and developed lengh
Nothing as long as the pressure pipe is not used for potable water as you cannot make a direct connection and depending on the GPM flow what size the larger sewer pipe is as 1 GPM (pumping) is considered 1 fixture unit when sizing the drainage system ALSO make sure the pumps system enters at a right angle 45 deg so your not eroding the side of the larger pipe out
Check pipe size for hot water or if galvanized pipe used, pipe could be clogged inside with rust and scale.
The recommended water heater pipe size for optimal performance and efficiency is typically 3/4 inch in diameter. This size allows for sufficient water flow and pressure to meet the demands of the water heater, ensuring it operates efficiently.
The speed at which water flows through your system depends on various factors such as water pressure, pipe size, and any obstructions in the pipes. Generally, water flows at a rate of about 8-12 gallons per minute in a typical household plumbing system.
To determine the appropriate pipe size for accepting 45 gallons per minute (gpm), you can refer to flow rate charts that correlate flow rates with pipe diameters. Generally, for a flow rate of 45 gpm, a pipe size of 1.5 inches in diameter is often sufficient for standard applications, assuming typical water flow conditions. However, factors such as pipe material, length, and pressure drop requirements can also influence the final choice, so consulting with a plumbing or engineering professional is advisable for specific applications.
If the electric motor requires 2 hp to run, then you need to supply it with no less than 1,492 watts of electric power. It makes no difference what job the motor is used for.
