The water flowing through a 2.1 cm (inside diameter) pipe flows out through three 1.1 cm pipes. (a) If the flow rates in the three smaller pipes are 25, 19, and 10 L/min, what is the flow rate in the 2.1 cm pipe

The flow rate of air through a through a pipe is 0.02 m5/s. a pitot static tube is placed in the flow. the radius of the pitot static tube is 1 mm. assuming the flow to be steady and the air to be at 300k, calculate the difference in total and static pressure if the diameter of the pipe is: (a) d 0.1 m d 0.05 m (c) d 0.01 m

The crank case of an automobile is 80 cm long 30 cm wide and 10 cm deep. find out the rate of heat flow from the crank case to the atmosphere when the automobile is moving at 90 km/hr. assume that the vibration of the engine and the chassis iaduce the transition from laminar to turbulent boundary layer may be considered over the entire surface. also find out the drag force on the total surface of the crank case. take the same average convective heat transfer coefficient and average shear stress for front and rare surfaces as for the bottom rnd sides crank case surface temperature is 75°c and atmospheric air temperature is 5 c

An industrial centrifugal air compressor has 34 radial blades that has no pre-whirl. the tip speed of the blades is 300 m/s, and the radial component of the air velocity at the tip is 150 m/s. air is inducted at 101.3 kpa and a stagnation temperature of 305 k. the mass flow rate is 3 kg/s. consider the power input factor to be equal to 1.04 and a stagnation temperature at the compressor exit of 370 k, if the flow is isentropic. assume cp-1005 j/kg.k. find the power input to the compressor (in kw)
