A 2.1 m diameter sewer is laid on a slope of 0.0032 m/m. If the Manning's Coefficient for the sewer is equal to 0.015 at all depths and flows, determine:
a) flow (Q) and velocity (V) when the sewer is flowing full,
b) Q and V when the sewer is flowing at a depth of 0.7 m,
c) Q and V when the flow in the sewer is at 60% of its capacity, and
d) V and depth of flow when Q = 1.6 m3 /s
A large pipeline with a 1.200 meter inside diameter carries oil similar to SAE 10 at 110 degrees celcius (sg=0.8). Compute the volume flow rate required to produce a Reynolds number of 3.60 x 10 ^4.
A stream of Refrigerant-134a at 1 MPa and 12 C is mixed with another stream at 1 MPa and 60 C. If the mass flow rate of the cold stream is twice that of the hot one, determine the specific volume of the exit stream.
A water pump can generate a pressure diference ΔP (psi) given by ΔP=145-0.1Q2, Q is the flow rate in ft3/s. It suplies a pipe of diameter 20", roughness of .5 inches and length of 2500 ft.
If the tangents intersect at an angle of 40 degrees, what is the highest degree of curve that can be used?..how to solve this problem using chord basis formula?
THe upper end of the spring is welded to the lunger and the lower end is welded to the base plate. If the plunger is lifted 1.5" above equilibrium and released from rest, calculate its velocity as it strikes A.
An I-section beam 350*200mm2 has a web thickness of 12.5mm & a flange thickness of 25mm - Sketch the shear stress distribution across the section.
A floor slab has a fundamental bending frequency of 10Hz. A shaker is placed at the centre of the slab for a dynamic testing. The tests confirm that the slab displays a damping ratio of 2% of critical.
Water flows down a spillway at the rate q = 15 m^3/s into a horizontal channel where v1 = 20 m/s. Determine the depth of flow in the channel y2 that will casue the hydraulic jump to occur in the channel. Determine the headloss hL in the jump.
A hollow rectangular steel beam is 18 cm deep by 10 cm wide, outside dimensions. The walls are 2 cm in thickness. From the shear and moment diagram, the maximum vertical shear on the section is 180 kN
A new rural by-pass has been proposed for a small town, with three possible routes under consideration. Using the data in the table below and the procedures in WebTAG (see the link below), undertake an economic appraisal of the proposal, comparing it..
A batch dryer with a grain depth of 20 inches contain 21,000 pounds of 20.7% (wb) moisturecontent shelled corn. An airflow of 75,000 pounds dry air per hour is supplied at a temperature of 175°F. The ambient air is 55°F at 100% relative humidity.
assume that the earth is a smooth sphere and a steel band wrapped around the equator. if 10ft of steel is spliced into the band, what will be the resulting height of the band above the earth surface
