A 22-year-old student has to have a physical examination to certify that he is able to participate in interscholastic athletics.During the cardiovascular examination,you report his heart rate as 60 beats/minute and his arterial blood pressure as 118/68 mm Hg.According to echocardiographic study,his end-diastolic volume is 150 mL and his end-systolic volume is 60 mL. Starling forces are measured across a systemic capillary wall,and the following values are obtained:

If the reflection coefficient for protein (

)across this capillary wall is 0.8,what is the net pressure and direction of fluid flow across the capillary wall?
