Pg = 180 kPa 15 m PA = 500 kPa 37° 20 m-

It says my answer is partially correct. 264kPa is correct but it says 11.3m is not correct. What is the correct way to calculate this value?

1 Kerosene (20°C) flows at a rate of 0.04 m3 s in a 25 cm diameter pipe. Would you expect the flow to be laminar or turbulent? Calculate the entrance length

A horizontal smooth-walled cylindrical pipe has diameter 0.04 m. Water flows along the pipe with a flow rate of Q 2 x 10-4 m³ s-¹. = For water, take the kinematic viscosity as v = 10-6 m² s¹ and the 10³ kg m-³. density as p = (a) Calculate the Reynolds number and establish whether the flow is turbulent or not. (b) Show that λ = 0.035 is a good approximation of the Darcy friction factor for this flow. (c) Calculate the shear stress at the wall of the pipe, and hence find the magnitude of the drag force exerted by the water on a length 2 m of the pipe. L =
