2900 rpm instead of 1440rpm motor

what will be the current drawn if we use same kw rating but different rpm motor??
What has RPM to do with current? Torque will increase as speed decreases. At the same line voltage if the current changes, will the power rating remain the same?

sir,
pump design is @1440 rpm but motor connected later is 2900rpm 15 kw. so definately linw current drawn will be around 60 to 70 pc more then wht 1440 rpm 15kw motor.wht will be the effect on pumping application and motor that i wanted to know??
If the pump is designed for 1440 RPM and consumes 15 KW, connecting a 15 KW 2900 RPM motor to it will severely overload the motor and cause a burn out.

If the pump is designed for 2900 rpm with 7.5 kw motor and we want to run the pump in 1440 rpm with 7.5 kw motor what will be the result
