Question: Sebuah piston berdiameter d = 1 5 0 m m bergerak dalam sebuah silinder liner berdiameter D = 1 5 0 , 2 m m

Sebuah piston berdiameter d=150mm bergerak dalam sebuah silinder liner berdiameter D=150,2mm dengan kecapatan rata-rata U=6ms. Minyak pelumas dengan specific gravity sebesar 0,92 memiliki viskositas kinematik sebesar 2,810-5m2s. Bila panjang piston sebesar 300mm, maka tentukan daya yang hilang akibat gesekan! (note: densitas air =1000kgm3)
Sebuah piston berdiameter d = 1 5 0 m m bergerak
