Water enters the constant 130 mm inside-diameter tubes of a boiler at 7 MPa and 65˚C and leaves the tubes at 6 MPa and 450˚C with a velocity of 80 m/s. Calculate the velocity of the water at the tube inlet and the inlet volume flow rate. Hint: the mass flow rate remains constant.
Q1:
A. One of the researchers discovered a patent related to the development of a
certain software module in mobile devices, and when he emailed one of the
companies producing these devices, they asked him to send the research to try it on
their devices, and after a while this researcher discovered that his discovery was
used by this company without referring to him or buying this discovery, What do
you think about the above.
B. As a quality control engineer in one of the electrical appliance factories, I
discovered that the technical worker responsible for inspecting one of these
products seals its validity without inspecting it. when I filed a complaint with the
administration, the administration neglected the complaint, arguing that there was
no time to inspect it again due to lack of time to prepare the consumer.
1. What are the consequences of this action, it is possible that there is a bad in the
product due to lack of examination.
2. The actions that you should take because of…
The pump shown in figure delivers water from the lower to the upper reservoir at arate of 2 cfs. The energy loss between suction inlet and the pump is 6 lbf-ft/lbf and betweenthe pump outlet and the upper reservoir is 12 lbf-ft/lbf . Both pipes are 6-inch schedule 40steel pipe. Calculate (a) the total head on the pump and (b) the power delivered by the pumpto the water
