Question

The unit of pressure one bar is ___________

(a) 1 Pascal

(b) 1 kilo Pascal

(c) 100 kPascal

(d) 1000 kPascal

This question was posed to me in homework.

My enquiry is from Fluids in Motion topic in section Fluid Flow and Mixing of Bioprocess Engineering

Answer 1

Right answer is (c) 100 kPascal

Easiest explanation: A bar (b) is a metric measurement unit of pressure. One bar is equivalent to ten newtons (N) per square centimeter (cm^2).

1 bar = 100,000 Pascal = 100,000 N/m^2 = 100,000 N / (100*100cm^2) = 10 N/cm^2.
