1. The flow of water in a 3-mm-diameter pipe is to remain laminar. Plot a graph of the maximum flowrate allowed as a function of temperature for 0
2. Carbon dioxide at 20 °C and a pressure of 550 kPa (abs) flows in a pipe at a rate of 0.04 N/s. Determine the maximum diameter allowed if the flow is to be turbulent.
If the spring extends0.116 in. when the instrument is on Mars, what is the Martianacceleration of gravity? How much would the spring extendon the moon, where g 5.471 ft/s2?
a 0.5-m3 rigid tank containing hydrogen at 20oc and 400 kpa is connected by a valve to another 0.5-m3rigid tank that

oxygen o2 gas within a piston-cylinder assembly undergoes an expansion from a volume v1 0.01 m3 to a volume v2 0.03
1 .The mechanical properties of cobalt may be improved by incorporating fine particles of tungsten carbide (WC). Given that the mod- uli of elasticity of these materials are, respectively, 200 GPa (30 x 106 psi) and 700 GPa 2. (a) What is the dis..
a solid shaft 200 mm in diameter rotates at f 20 revsec and is subjected to a bending moment of 21p kn.m. determine
Determine the drive point impedance of a semi-infinite string on a suspension if- The suspension is purely elastic. Explain the behavior in different frequency ranges. The suspension is purely dissipative. Why is the result complex in this case?
A gas turbine power plant operates on the simple Brayton cycle between the pressure limits of 100 and 1600 kPa. The working fluid is air, which enters the compressor at 40 degrees Celsius and leaves at 650 degrees Celsius. Using constant specific hea..
The drag, d, on a washer-shaped plate placed normal to a stream of fluid can be expressed as D = f(d1, d2, V, μ, ρ) where d1 is the outer diameter, d2 the inner diameter, V the fluid velocity, µ the fluid viscosity, and ρ the fluid density. Some ..
A steam power plant implements an ideal reheat Rankine cycle. Steam enters the inlet of thigh-pressure turbine at 8 MPa and 450 Celsius and the inlet of the low-pressure turbine at 0.5 MPa and 500 Celsius. The condenser operates at 10 kPa.
The parting line in injection molding is which one of the following: (a) the lines formed where polymer melt meets after flowing around a core in the mold, (b) the narrow gate sections where the parts are separated from the runner, (c) where the clam..
