Algebra
A 1,260-galloon tank is filled by two pipes in as many as the smaller pipe brings in galloons per minute. How long will it take each pipe to fill the tank if the larger pipe brings in one galloon per minute more than the smaller pipe?

Normal shock wave
1. Consider a NSW with a downstream-upstream temperature ratio of 3.5 what is the mach number upstream and downstream of the shock? Show your solution.
2. The flow just upstream of a NSW is at SSLC and the mach number downstream is 0.6152 determine the pressure, temperature, density, velocity, and the total pressure and temperature. Show your solution
3. The mach number behind of a NSW is 0.4752
What is the mach number in front of the wave and the pressure ratio across the shock? Show your solution.

Beam Deflection
hdr.jpg" />
hi please help me with my assignement.
this beam made of steel with moduus youg of 300 gpa, cross sectional area A1 =10.10^-6 m2
A2 = 20. 10^-6 m2.
length L1 = 2m
Length L2 =1,8 m.
at he level that is very rigid ring mounted to apply the load F=8 KN.
questions :
1.calculate reaction pedestal points A and B
2. stresses that ocur in cross section A1 and A2
3. the displacement Point C.

thermo
A spherical container of negligible thickness holding a hot fluid at 1400
and having
an outer diameter of 0.4 m is insulated with three layers of each 50 mm thick
insulation of k1 = 0.02: k2 = 0.06 and k3 = 0.16 W/mK. (Starting from inside). The
outside surface temperature is 300C. Determine (i) the heat loss, and (ii) Interface
temperatures of insulating layers.
