What is the pressure loss due to friction for a 30 m length

Question

Problem 1:

Calculate the total equivalent length of 1-inch wrought iron pipe that would produce a pressure drop of 70 KPa due to fluid friction, for a fluid at a rate of 0.05 kg/s, a viscosity of 2 cP, and density of 100 kg/m³.

Problem 2.

Sulfuric acid with a density of 1980 kg/m³ and a viscosity of 26.7 cP is flowing in a 35 mm diameter pipe. If the acid flow rate is 1 m³/min, what is the pressure loss due to friction for a 30 m length of smooth pipe.
