Calculate form-resistance coefficient and form loss in the following pipe specials if the pipe discharge is 0.15 m3 /s: (a) Pipe bend of 0.3-m diameter, bend radius of 1.0 m, and bend angle as 0.3 radians. (b) A 2/3 open sluice valve of diameter 0.4 m. (c) A gradual expansion fitting (enlarger) of end diameters of 0.2 m and 0.3 m with transition length of 0.5 m. (d) An abrupt contraction transition from 0.4-m diameter to 0.2-m diameter.

Water at 55c flows across a flat plate whose surface temperature is held constant at 95c. if the temperature gradient at the plate's surface for a given value of x is 18 c/mm, find a) local heat transfer coefficient. b) heat flux

Hydraulic fluid with a sg. of 0.78 is flowing through a 1.5 in. i.d. pipe at 58 gal/min. the fluid has an absolute viscosity of 11.8 x 105 lbf-sec/ft2. is the flow laminar, turbulent or within the critical range? give both a numerical reynolds number and a term answer.
