Given that A can complete the work in 10 days, the work rate of A is
1
10
10
1
​
of the work per day.

Since B is 50% more efficient than A, B's work rate will be:

B’s work rate
=
1.5
×

B’s work rate=1.5×

Now, to find the time B takes to complete the entire work alone, we calculate:

So, B alone can do the same job in

1. TEAM DETAILS & PROBLEM STATEMENTS PS Code: PS-SC1     Problem Statement Title: MICRO HYDRO POWER TURBINE SYSTEM Team Name: GRYFFINDOR Team Leader Name: MONISH B Institute Name: RAJALAKSHMI ENGINEERING COLLEGE

2. ABSTRACT The main objectives of this project is to fabricate a small scale modified tesla turbine with improved torque. It is used in domestic water pipelines to generate electricity. The Tesla Turbine’s principle of operation is based on adhesion and viscosity instead of drag force. The efficiency of this turbine is relatively high Theoretically 81% (Turbulent flow) . The torque of the turbine is increased by our modifications in the design of the pre existing Tesla turbine without affecting the efficiency.

12. IDEA APPROACH DETAILS Use cases: To provide efficient small scale power generation in buildings and flats where the output can be used to power the common light bulbs. To charge electronic appliances in domestic applications. TARGET AUDIENCE: Gated Communities and Resedential houses. Small scale commercial building. Show stopper: The novelty in our modified tesla turbine is increasing the torque produced by providing slots in the discs. The modified tesla turbine works on both drag force and adhesion principle. So the torque is increased without affecting the flow and efficiency
