Fuel rate and energy input: Assume this vehicle cruises on level highway at 70 miles/hour and crankshaft speed of 3500 RPM. The vehicle is assumed to have a fuel economy of 35 miles per gallon, where gasoline has a heating value of 114,000 Btu/gallon.
Determine:
a) the fuel consumption rate (gallons/hour),
b) combustion energy per thermodynamic cycle (Btu),
c) specific heat input per thermodynamic cycle (Btu/lbm).

Amixture of slurry and mud is to be pumped through a horizontal pipe of diameter 500 mm. the fluid behaves as a bingham plastic with a yield stress of 30 pa and viscosity 0.04 pa. s. describe the effects of the shear stress through a transverse section of the pipe by plotting the variation in shear stress and velocity profile: (i) just before the slurry starts to move (ii) as the slurry flows when the pressure gradient is double that in part (i)

Apressure vessel with an r/t 20 cannot be treated as thin walled vessel. a)-trune b)- false

To design a steam turbine to produce 12,000 hp power. a engineer comsiders using a steady state stean low st 1160fr and engineer considers using a steady state steam flow at 1160°r and 450 psia to drive this steam turbine. the exhaust of the steam is cooled by the lake (vacuum). heat losing to the surroundings is measured at a rate of 555.55 btu/s. (a) sketch the system with the given conditions. (b) neglecting kinetic and potential energy changes from inlet to exit, determine the volumetric flow rate of the steam at the inlet, (ft'/hr). must clearly show unit conversions at crtical terms.
