The invention discloses a determining method for exhaust mass flow of a spacecraft under the low pressure in a cabin. Under the condition of the low pressure in the cabin, the length of an exhaust channel and viscous loss of gas flowing in the channel cannot be neglected. The flowing of one-dimensional isentropic flows and pipeline flowing considering the friction are coupled, and a coupling computation cabin for the exhaust mass flow of the spacecraft under the low pressure in the cabin is established. The iterative solving is performed on the coupling model to obtain the exhaust mass flow by adopting a method of traversing channel inlet Mach number, so the problem that the exhaust mass flow is difficult to obtain under the low pressure in the cabin is solved.
