General safety guidelines

Safety guidelines are the set of rules and codes that must be followed in the workplace for the occupational safety of workers, the machines, and the equipment that are present inside the workshop premise. There are many unsafe conditions and hazardous materials inside the workshop that makes prey for certain risk factors associated with health conditions. Extreme safety precautions must be taken inside the work area just like the precautions and practices that are been followed for Corona Virus Disease 2019 (COVID-19). People can also educate themselves by joining various health programs and camps. These will provide them with the necessary skills and knowledge about safety awareness. Occupational Safety and Health Administration (OSHA) thrives to create a safe and healthy environment for the workers working in the industries and provides them with proper education and training.

Question

answer first item only

A pump rated at 65% efficiency is used to transport water from a large open
reservoir to a point 10m above at a rate of 450 L/min, into a vented tank.
Assuming friction is negligible and that the efficiency of the motor is 77%, how
much electricity is quired to keep the process running for 24 hours?
29.37 kWh
35.28 kWh
56.71 kWh
43.21 kWh
The velocity of water is measured using an orifice meter (throat diameter =
0.06m) in a 0.31-m pipeline. The measured pressure drop across the orifice is
75 kPa. The Reynolds number at the orifice is nearly:
250000
375000
500000
125000
